everything about old kitty is fine (normal bowel movements, no problems in the litter box). I've had fecals done on her a few times since we got a third cat (who she just loves btw). Nothing at all abnormal has ever shown up.
I'd hate the thought of losing her because she gets so scared when you take her to the vet. She has skin cancer because she is all white but luckily it has not recurred in almost 5 years now. This has nothing at all to do with weight but it has a lot to do with why she is so scared of the vet. Her teeth are all still in place and appear to be sound, no red gums or anything and she had them cleaned after one of the recent cancer surgeries.
She is an indoor cat so I don't fear she has a disease or anything (she doesn't got outside much anyway because of the skin cancer issue). I hope it doesn't recur because I dread having to deal with it as it requires major surgery (she's had 3 surgeries for this problem in the past 7 years - all required major blood work, etc. - no abnormalities but I was told that the chances of recurrence are 100% *sigh*).
We're trying to fatten her up but it isn't working very well but she is sure enjoying it. :)
I'll try not to worry about it anymore. I'll worry when/if the skin cancer comes back again and just let her be until such time may come.
She is an odd-eyed cat, 1/2 Siamese and 1/2 something else. Here is a picture of her taken a couple of years ago (she has aged a lot even since this picture was taken even I've noticed).
Thanks again you guys, you've put my mind at rest! :)
