Is it ok to give cats raw liver if they have kidney failure symptoms
I would recommend that you visit a holistic vet to determine the appropriate diet for your cat so as not to affect the kidneys more, since a high protein diet is usually recommended for kidney problems. Read more: http://www.allthebestpetcare.com/kidney-failure-in-cats.
Check with your vet. You don't want to cause additional problems for a cat that's already sick.
Liver is high in uric acid and probably nor so good for a cat with kidney problems. Like the others said, check with your vet. In the meantime I probably wouldn't give it to her.
