Our DCat is probably about 17.5 yrs (not sure - rescue). Took her to vet recently because she was drinking a lot: turned out her thyroid hormone level was at the upper limit of normal. After two weeks of anti-thyroid treatment she's her happy self again. But vet also found an ill-defined mass in her abdomen. Could be lymphoma. We have to decide whether to put her through ultrasound and biopsy, then maybe cytotoxics, possibly oral ones with steroids, to prolong her life.
Does anyone have experience of this? I wonder if it would be better to give her lots of meat and fish (usually rationed for the sake of her teeth), cuddles, cat milk and toys, as long as she's happy. Trying to buy more time will involve vet visits, blood tests etc which she hates. She is insured so we could probably claim most of the costs; that won't dictate the decision.
Can anyone advise?
