Does anyone know a good cat food for cat's that need extra protein? My cat Blue has been diagnosed with some sort of kidney issue, we won't know exactly what she has until they do an ultrasound. But in the meantime she is very low on protein so before we do anything else we went to get her protein up. The vet put her on Enacard which I have to give her half of everyday, probably for the rest of her life. The best way I've found after much experimentation, is to wrap it in a small piece of turkey. She eats it right up pill and all. I also figured if she's low on protein the turkey would probably be good for anyway. But I only give her a small piece so I'm interested in buying her a food that she can eat everyday that will help get her levels up. My other question is if it is okay to give my other cat a high protein food as well since they both eat each others food from time to time. I don't know if extra protein would be bad for a cat that isn't loosing it.
