Upon diagnosis of kidney failure it’s probable that your cat will be switched to a special "kidney" food, designed to be nutritious without over-working the failing kidneys. Such foods will be low in phosphorous and protein. When Paris was first diagnosed with CRF both my cats were switched from Hills w/d and Hills c/d food to Hills k/d formula , which is specially designed for cats with kidney disorders. I know that there are other brands of prescription foods targeted to be beneficial for specific ailments. It doesn’t really matter which prescription food your cat is on, because if you’re dealing with diabetes and kidney failure, the kidneys take priority.
I am very frustrated because he’s always eaten raw food (my vet doesn’t approve of that, BTW). If I take him back to her, I’m sure she’s going to suggest some Science Diet garbage and I don’t want to go that route. I am working under the assumption that this CANNOT be a grain allergy because his food has always been grain-free. I am also assuming that it’s a chicken allergy, because that is one of the most common allergens and also the variety I’ve fed him the most often (probably too often, in retrospect, I should have been rotating more frequently).
5mg a day was too much and he was having bad side effects, extreme lethargy, he stopped eating,and drinking and his diarrhea actually got worse. Half a pill ever other day was not enough his stool was normal the first day then back to diarrhea the second. Half a pill mg a day seems to be the formula that works for him. He tolerates it well,and his stool remains normal. Mischief is much more active and healthy now,and is actually gaining weight. I am very pleased. Like I said I think it saved his life. Also the drug is very inexpensive $10 bucks a month
