I have a cat that is I think about maybe 12 yrs. old. She was a feral and it took me 6 yrs to get her to come in the house on her own. She has been sickly lately, and I'm not sure what to do about it. I know she needs to see a vet and I intend to bring her. She is not grooming at all like she used to and now she is dragging her butt around once in a while, she uses the litter box ok, and she is eating ok but drinking alot of water. She had a cyst on the side of her face that she popped and that is now healed. Her eye on the side of the face that had the cyst is red and kind of bulging. She pants and her tongue is always hanging out. She sneezes a lot but doesn't seem to cough much. In short she looks really sad. She is getting around ok. I feel really bad for her. I know it would be a really big stress just to get her into a carrier and to a vet and I really don't want to stress her anymore than I have to, but I guess she will have to go see him. At her age would it be feaseable to put her through all the tests? Or should I just let her go.
