I adopted my cat recently so I do not know her health history. When I adopted her she was considered a senior cat. She had all of the symptoms listed here loss of appetite pale gums--even her nose was a dull shade of pink--not too bright at all. She was also quite lethargic and did not seem at all interested or was simply unable to jump. I have taken a number of homeopathic remedies myself so I have a pretty good idea of how they work. What makes homeopathy remedies ideal for animals is that they are very easy to administer. I shook the bottle vigorously many times over the course of her treatment to increase the remedy's potency since I figured she probably had this problem for quite a while as she is an older cat. I also sprayed the remedy directly on her wet food rather than in her water because I need to change the water every couple of days. I think this works better than spraying it into the water because she licks her food as she eats it. As a result I think she got more of the remedy this way. Now her nose and gums are a much brighter shade of pink she jumps on the table and into the bathroom sink to play with the running water and she also eats much more. She is a senior cat but I think this remedy will prologue her life as well as extend the quality of it.
