My friend has just taken in a cat that has been living rough near her for 3 years. She took her to the vet because her feet were bleeding and the vet diagnosed pododermatitis and gave her a steroid injection which didn't work then prescribed prednisone but the cat vomited blood so my friends stopped the tablets, my friend is getting on in years and is disabled, the vet rather bluntly told my friend that the cat will probably have to be put to sleep, I was just wondering if there is any chance the cat could live with this condition or would it be cruel to keep her going
