How to Help your Cat Fight Cancer Naturally

How to Help your Cat Fight Cancer Naturally


If only cats really had nine lives!


While their impressive resilience will always surprise us, cats can become seriously ill and need a boost from their human companion in order to heal themselves.


Unfortunately, cats are not immune to cancer. Much like humans, they can develop many types of tumors and cancers.


If you have just received the bad news that your cat is fighting cancer, know that we are very sorry and hope that this text will help you better understand the situation.



As part of my job as an animal health technician, I have been able to assist with several surgeries for mass removal in animals. With the proper care and the endless love of their owner, animals can surprise us and bounce back very quickly.


This article has been put together to detail the causes of cancer in cats, the different types and symptoms. Read on to learn more about the natural treatments that exist to help cats fight this subtle demon. We actually suggest natural ways to fight your cat’s cancer and show you how to shrink a tumor with our holistic products.



What are the causes of cancer and tumors in cats?


You may already know that a tumor is a mass formed by the uncontrolled multiplication of a certain type of cell. It’s difficult to pinpoint the exact causes of cancer in cats, however, certain risk factors are known, such as obesity, second-hand smoke and some viruses.


We talk about cancer when a tumor is said to be malignant, that is to say that it grows quickly, tends to migrate through the bloodstream (metastases) and is at risk of recurrence. That said, cats can develop benign tumors, which are non-dangerous masses.


Risk factors for cancer in cats:


  • Overweight
  • Lack of physical exercise
  • Secondary smoke
  • Prolonged exposure to the sun
  • Feline leukemia (leukosis) virus (FeLV)
  • Feline immunodeficiency virus (F.I.V.) also known as cat AIDS


Since the latter two viruses are contracted through contact with other cats, it’s not wrong to say that letting a cat wander outside indirectly increases its risk of developing cancer.


How common is cancer in cats?


It is said that one in five cats will develop cancer in their lifetime.


Generally, older animals are at higher risk of developing cancer, however, in cats with viruses such as FeLV and F.I.V., they can develop cancers at a young age.


Among the most common cancers in cats, we find lymphoma and mammary tumors in females.



How to detect a tumor in a cat?


Whether benign (harmless) or malignant (cancer), a tumor is detected most of the time by feeling a lump under the skin. Only a laboratory analysis of cells can confirm the nature of this.


Despite what you might think, a benign tumor can also sometimes cause symptoms. For example, a benign mass in the brain could put pressure on certain structures and thus lead to neurological signs.


That said, a tumor on an internal organ can be difficult to detect and that is why it is important to pay attention to the following signs.



What are the symptoms of cancer in cats?


As in humans, the signs of cancer vary depending on the system or organ affected by the tumor(s). As mentioned earlier, you might notice a lump under your cat's skin, which is a good indicator. Pet owners should also take particular note when animals change their normal habits.


Here is a non-exhaustive list of signs of a tumor in cats:


  • Lump under the skin
  • Abnormal odors
  • Vomiting
  • Diarrhea
  • Wounds that do not heal
  • Reduced appetite
  • Weight loss
  • Cough or difficulty breathing
  • Fatigue, lethargy
  • Increased thirst
  • More frequent urination
  • Pain


If your cat has any of these signs, we recommend that you consult a vet.


We invite you to learn more about these 10 signs of cancer in cats, because early detection can be the best way to save your beloved companion.



How long can a cat live with cancer?


As you can imagine, there is no precise answer to this question. We could be talking about a few weeks or a few years. Only your vet can give you a prognosis according to your kitty cat’s particular case. The type of cancer, its stage at diagnosis and the general health of your cat are all factors that can affect life expectancy.



What are the most common types of cancer in cats?


Many cancers found in cats are also found in humans. They are mainly classified by the system in which the uncontrolled cells develop. Skin cancer, breast tumors and bone cancers are also found in cats.



Lymphoma in cats


Lymphoma is a cancer that affects the lymph cells of the cat, more specifically the lymphocytes (white blood cells). It is the most common cancer in cats and there are different forms, depending on the organ that is affected. This is because, in actuality, lymph is found throughout the body. It usually appears suddenly and is seen largely in older cats or those with the feline leukemia virus. The life expectancy of a cat with lymphoma is between two months and two years.


Among the different types of lymphoma in cats, we find intestinal lymphoma, mediastinal lymphoma, renal lymphoma, and small and large cell lymphomas. Intestinal lymphoma, which affects the digestive tract, accounts for about ⅔ of lymphoma cases in cats.


Skin cancer in cats (melanoma and malignant melanoma)


Melanomas (benign or malignant) are skin tumors. They generally develop on the cat's head (eyes and ears), its neck or hind limbs. Malignant melanomas are quite rare in cats, but unfortunately they are also aggressive. They tend to recur when removed surgically.


There are other types of skin cancer in cats as well. They can develop basal cell carcinomas, mast cell tumors and fibrosarcomas. Some fibrosarcomas can also develop at the injection site following a vaccine.


This happened to my friend's cat. Following its vaccination, the small lump under the skin never went away and, after having it analyzed, the vets realized that cancer was developing. But don't worry, it's very rare.


Bone cancer in cats (osteosarcoma)


There are different types of bone cancer, but osteosarcoma is the most common. This cancer is characterized by an uncontrolled multiplication of bone cells (often in the long bones) and usually causes pain, swelling and lameness. Life expectancy is more encouraging for this type of cancer in cats than in dogs.


Cats with osteosarcoma can usually live 1 to 4 years, depending on several factors, such as the location and stage of the disease. Although rather rare, this type of cancer is aggressive.


Liver cancer in cats


Liver cancer affects this organ which is involved in the digestion process. A cat with this type of cancer may have digestive symptoms such as vomiting and loss of appetite. Not all masses in the liver are cancerous. An ultrasound and biopsy can therefore provide more information on the nature of a lump on the liver.


When we talk about liver cancer, we mean the organ affected by the disease. Again, there are several types of liver cancer. Here are a few examples: carcinomas of the bile ducts, sarcomas and myelolipomas.


Learn more about liver cancer in this comprehensive article on the topic.


Bladder cancer in cats


Fortunately, this type of tumor is very rare in cats. However, if a cat shows symptoms of a major UTI without resolution after treatment, it would be important to do additional tests (such as an ultrasound) to rule out cancer. The symptoms are very similar.


Male cats and those that are  obese are more at risk of developing this kind of cancer.


It is known that between 50% and 70% of bladder tumors in cats are described as transitional cell carcinomas, referring to the cells that line the inner wall of the bladder.


Stomach cancer in cats


A tumor can develop in the stomach. There is also a type of lymphoma that affects the digestive system. In all cases, a cat with cancer in the stomach would show signs such as weight loss, vomiting (sometimes tinged with blood) and loss of appetite.


It is reported that the majority of stomach tumors are malignant, yet they have the ability to spread throughout the body and create what is called metastasis. This is never good news. Fortunately, these cancers are not common in our kitties.


Bowel cancer in cats


When a tumor develops in the intestines of a cat, the cat may have symptoms such as diarrhea and pain upon touching its abdomen. If the tumor becomes large, it is even possible for it to block intestinal transit, which complicates the situation.


Bowel cancer is often diagnosed in cats between the ages of 10 and 12.


Male cats are more at risk than females and some breeds are also more susceptible to this type of cancer. In particular, I’m thinking of Siamese cats, who are 8 times more likely to develop intestinal cancer than other feline breeds.


Oral (mouth) cancer in cats


The most common oral cancer in cats is squamous cell carcinoma. It represents more than 75% of oral feline tumors.


Squamous cell carcinoma of the skin in cats


Although theoretically a skin cancer, this type of cancer often develops in the oral cavity of the cat. It is also observed in the nose and ears. This disease is often fatal, as surgery is complicated due to its location, and its progression can interfere with the cat's ability to eat. This kind of tumor responds more or less to chemotherapy.


Indeed, the life expectancy of a cat with an oral tumor is a few months, up to one year. The malnutrition it causes leads to a decline in the health of the sick animal.


Learn more about oral cancer in cats here.


Lung cancer in cats


Lung cancer itself is quite rare in cats. However, several other types of cancer can migrate to the lungs (metastases). All respiratory symptoms in cats (coughing, difficulty breathing), especially in older cats, should be analyzed quickly by a vet, as the situation can change very rapidly and become serious.


In fact, older cats are at risk of developing this type of cancer. Persian cat breeds are also more likely to develop it. As in humans, second-hand cigarette smoke can cause lung cancer in our animals.


Pancreatic cancer in cats


As the name suggests, pancreatic cancer attacks this organ which is involved in the digestion and production of certain hormones, such as insulin. There are different types of pancreatic cancer, depending on the type of cells that develop uncontrollably. Symptoms will often be digestive, such as vomiting, diarrhea, and weight loss. The prognosis is generally poor, while the diagnosis is often made too late.


Unfortunately, just like in humans, pancreatic cancer can be very severe. The life expectancy of affected cats ranges from a few weeks to a few months. The reason for this is that when this cancer is diagnosed, it is often too late and there is already metastasis throughout the body.


Breast or mammary cancer in cats (mammary gland carcinoma)


This type of cancer is very common in cats and affects its mammary glands. 85% of these tumors are reported to be malignant. It’s a very aggressive cancer that requires surgery from the start. As in dogs, this type of cancer is more often seen in non-sterilized females, although it is possible in sterilized females.


In fact, sterilizing a female cat before the age of 6 months reduces her risk of developing breast tumors by 91%! That’s not insignificant, is it?!


Cats have 4 mammary glands on either side of their abdomen, and tumors can develop in any of these glands. Sometimes chains of tumors are found in this region too.


Leukemia (or leukosis) in cats


Feline leukemia is technically not a cancer in cats. It’s actually a viral infection that causes immunodeficiency and can cause cancer, such as lymphoma. In more severe cases, the virus can spread through the bloodstream to the bone marrow, white blood cells and blood platelets, making it look like human leukemia.


This virus, which is part of the same large family as HIV (but not contagious to humans), is transmitted between cats mainly via saliva.


Cats that venture outside are much more at risk of catching it, as it is a very contagious virus between cats. Mutual grooming, sharing litter or water bowls and sneezing are some of the means of transmission, among many others.


Fibrosarcoma in cats


Fibrosarcoma can appear anywhere, as it is a tumor that develops in the subcutaneous tissue and then in the muscles of the body. It does not usually cause pain on touching. This tumor tends to grow very quickly, to the point where it can ulcerate and become necrotic.


Cats diagnosed with fibrosarcoma can live for up to 3 years with the disease. That said, if the lump is detected early and surgery is done to remove it, a cat could gain several years!



How to treat cancer in cats?


You are probably familiar with the conventional treatments used in humans, namely chemotherapy and radiotherapy, which are also an option for our feline companions. Read on for natural options to help your cat through his fight against cancer, such as the PIPTOPET product and proper nutrition packed with antioxidants.


How to shrink a tumor in a cat?


Conventional treatments, such as chemotherapy and radiotherapy, are used to shrink the size of a tumor and kill the remaining cancerous cells after the surgical removal of a lump.


Chemotherapy and radiotherapy are invasive and attack both healthy and diseased cells. We suggest alternative natural products to optimize the fight against the cancerous cells, without impacting the healthy cells.


As the name suggests, chemotherapy is the administration of a chemical treatment, i.e. strong drugs, either intravenously or orally. Less than a quarter of animals show side effects from this therapy, unlike in humans.


Radiotherapy, also called radiation therapy, is when radiation is targeted at a tumor with the aim of completely destroying it or reducing its size. It requires several treatments and the animal must be anesthetized each time, as it must be completely still during treatment.


Surgery is often an option to consider. In fact, I personally assisted in a surgery to remove a lump the size of a tennis ball between the shoulder blades of a poor cat. This tumor had surprisingly grown in less than two months! The surgery was a success and was curative for this cat who is now in great shape.


Nevertheless, there are less invasive natural methods of treatment for feline cancer. See our suggestions below.


How To Shrink a Tumor in a Cat Naturally?


So, I have just described to you the classic and most known methods of shrinking tumors, whether in cats or humans.


Such as antioxidants and medicinal mushrooms.



How to treat cat cancer naturally?


The following natural alternative treatments can be used alone or in combination with conventional treatments. In advanced cases where surgery is necessary, natural medicine is a good complement. For people who don't want to inflict invasive therapy on their kitty cat, there are natural ways to fight cancer.


How do you shrink a cat's tumor naturally? Read on to learn about our alternative products.




It is a well-known fact that nutrition plays a major role in the well-being of any individual. A good diet helps strengthen the immune system, and some foods even help fight cancer both directly and naturally. You will find some examples below.


One thing to keep in mind is encouraging water intake, so that the animal maintains good hydration which is essential for the proper functioning of the body.


For example, you can offer your cat canned food and add to this a little hot water. Another important thing is to provide quality food that can be supplemented with omega-3s. This will help the animal maintain good muscle mass, which is just as important in its fight.




The normal action of the metabolism produces so-called free radicals, which are harmful to the body. These free radicals actually attack cells and can cause serious diseases, such as cancer. By having an antioxidant intake through food, we make sure we have control over these toxic molecules and therefore, we help prevent cancer.


It can therefore be a good idea to add certain sources of antioxidants to your cat's food, without drastically modifying its diet.


You could add a small amount of certain fruits and vegetables to its diet, such as broccoli, carrot and butternut squash. Be careful to cook them well beforehand.




Curcumin is the active ingredient found in the well-known turmeric. It is credited with anti-inflammatory properties and is even believed to have the ability to slow the growth of certain cancers.


It is therefore a noteworthy remedy for naturally treating cat cancer. Check with your vet if curcumin is right for your cat.


Medicinal Mushrooms


Mushrooms are part of a mysterious world, in harmony with the rest of nature. Some mushrooms are deadly, while others can literally save lives. Some people even see them as a miracle cure.


Care should be taken when using mushrooms as a natural treatment, and always  ensure the quality of the product. We do not recommend that you go into the forest and pick your own, as many mushrooms look alike and there are some requirements to picking them that are important to follow.


With that said, we're here to guide you and we've prepared for you several natural products with a base of medicinal mushrooms so that you can use their properties safely.


Medicinal mushrooms with anti-cancer properties include the popular chaga, shiitake and cordyceps.


These can be used alone or in conjunction with conventional medicines. They are excellent holistic options for cats.



A product made with natural ingredients


Perhaps you have consulted our last article on dog cancer and now know of birch polypore (Piptoporus betulinus)?


This medicinal mushroom works miracles. Our natural product PIPTOPET is mainly composed of this powerful ingredient.


The fungus, Piptoporus betulinus, promotes your cat's defenses during his fight to get rid of cancer cells without harming healthy cells in the body.


The product can even be used to promote your cat's immune system in the early stages of cancer. It can also be used to support your cat's health even in advanced cancer, since it allows your pet to maintain good overall health by stimulating its immune system. A good immune system can help protect your cat from secondary infections.

In addition, as a cat owner, you want to promotes the shrinkage of tumors, which is a major advantage in the fight against cancer. Do you want to help YOUR cat dissolves tumors ? 

At Zumalka what we offer is to help is PIPTOPET because it allows your pet to maintain a good quality of life naturally even in difficult times of illness.


Check out our website for yourselves where you can read the comments of our customers satisfied with the success achieved with this product.


Here is one of their story :


 “In August of 2019, our 8 year "KittyKat" was taken to the vet. She'd lost a ton of weight, and no longer wagged her tail for anything except breakfast.


She was quickly diagnosed with some unknown type of tumor, larger than a softball, in her abdomen.


We were given little to no hope, and told to take her home and spoil her until she couldn't take living any longer.


We could have had tests/surgeries/treatments done, but was told that because of her breed that the cancer was quite probably of a certain type and those things "might" add an extra 6 months of life.


And really, who wants to live an extra few months while sick on Chemo. So they prescribed her steroids to help keep her comfortable, but all they did was make her sick.


I came home from the vet and did a ton of research, decided to give Piptopet Cancer treatment a try, what have we got to lose?


Well, within the first week, I saw such a difference. She was happy and playful again.


A year and a half later, I can still feel the tumor there, and she never regained the weight, despite eating more than she used to, but she's thriving.


She has a few bad days now and then, but don't we all? She eats well, plays, enjoys walks, and belly rubs. I never thought we'd still have her around, but thanks to Zumalka and Piptopet, we've been given so much more time with our sweet girl.”

Our 12 year old cat has a malignant tumour in the spleen and it has spread to the liver, there is also some sort of tumour in the ear canal. The cat still seems to have energy, drinks and eats.

Is there a remedy that can reverse this or is it too late?

Vet “suggests” euthanasia.

My 19 year old Ragdoll has been diagnosed with gastrointestinal cancer and has a large mass pushing into one lung making breathing difficult. He is currently getting steroid injections. Can I give your product to my cat along with the steroid?


February 10, 2023

Thanks Michael, you’re off to a great start with your Piptopet order ! We can’t wait to hear good news from you and Pumpkin !


February 10, 2023

My cat Pumpkin has a mass on her large intestine. There was an unidentified fluid buildup surrounding her lungs and lower organs. It’s been drained since. She’s a 11 year old Maine Coon. I’m hoping she lives to be 21, like Pumpkin the first. Can PIPTOPET help her? She is eating and drinking water, but she’s losing a lot of weight. She’s been prescribed a steroid, than she doesn’t like, in hopes that it will shrink the tumor. Should we continue the steroid in conjunction with PIPTOPET? Any advice much appreciated.



May 23, 2022

Anyone reading this comment please know that the cancer being described by the author in the above statement IS NOT RARE. Please do not get your dog/cat vaccinated year after year after year; it is unnecessary and is only done to make pharmaceutical companies more money. My cat Amelia was diagnosed with Vaccine Associated Sarcoma in 2006; I still have her pathology report from LSU. She passed away from that horrible disease in May 2009 and I still feel guilty. There are thousands upon thousands of new cases reported to the USDA each year by veterinarians however these numbers only represent cases where the owners sought treatment.


March 29, 2021

Dear Giacinta,
We are so very sorry to hear that Misce is having to fight with Sarcoma. We understand how stressful this is. But we are happy to offer you natural solutions that can help in your pet’s battle with cancer! We will be sending you a private email so we can help him in a more personalized manner. We look forward to working with you!

A year ago my Misce had what looked like a blister on the top of his nose.  The pandemic had just started and so his vet appointment had been delayed. By the time he got to the doctors it had grown and started to bleed due to the scratching and touching in the area. It is a long story and it has been a long year but after 3 surgeries the diagnose sarcoma has returned and I just can’t afford anything else. Me she is spunky he’s doing great but I could see that the tumor is really irritating him as it is causing him to lose weight. I’m going to see a new vet and find treatment options that we could work with to prolong his life and keep him comfortable. Does this work well also with steroids just in case that is provided to us as an option?


September 10, 2020

Hi Diane,

MY cat, Lexi is 9 years old, diagnosed last week with a mass in her stomach. The mass has taken 90% of her stomach. She is vomiting and has lost weight. She is still eating but little and often. She is currently on steroid tablets – 1 a day. Can I give Piptopet to my pet? Will it shrink the mass in her stomach ?


September 10, 2020

Thanks for the splendid article, Veronique. This is quite well-written. I do agree on the tragedomedy of it all, but I think it’s an uphill battle, not a downhill one. So look alive, keep up the good work, all in all, some such, thank you thank you thank you.


August 24, 2020

Dear Barbara C,

Thank you for your comment and we hope this article was useful for you in helping your cat’s fight against cancer. The Piptopet will work well with other mushrooms however, we would need to have more specifics on what mushrooms are included in what you are giving. We have sent you a private email so we can get all the details and give your cat the best possible help!

Can this be used in combination with other mushrooms. I am giving my cat a multi mushroom complex . She had adenocarcinoma removed from the small intestine.


June 15, 2020

Hi Mary,

Thank you for your comment and excellent question. Our PIPTOPET remedy can for sure be given as prevention to cancer! Simply give a much lower dosage of 1 spray a day in the mouth or with water. This prevents the formation of cancer cells in the body and boosts the body’s natural defences and fighting power.
