i have one poorly cat....i got him to prevent him being put to sleep as a stray after an RTA where he lost an eye. still having problems from that 8 years on as in nerve endings making him scratch. he has cystitis, kidneys are getting worse, bleeding hocks and front joints where he sleeps so much, very dandruffy/dry skin. he is also losing weight. he doesnt seem to have much quality of life and his only pleasures in life are sunbathing and me. how do you know when theyve had enough, how do you read the signs they give you? all advice greatly appreciated.
