Hi, last week the vet told me that my 12 year old cat is in kidney failure. I asked for prognosis (for extended life), he said "not good, but not impossible". She is a happy cat, nothing that will tell you something is wrong except occasional bladder infections and throwing up about once a week. I tried to get her to eat Hills K/D and Royal Canin's kidney support food. She won't even touch those. I tried Hi-Tor Neo Diet, which has low phosphorous Nope, not that either. my vet's out til Tuesday, but his wife said "she'll eat wqhen she gets hungry", but I know this girl, she's very stubborn, and I know how quickly hepatic lipidosis can set in, so I will not let her go even a day without eating. I stumbled upon Performatrin, which had a phosphorous % of .18, which I thought was great, so I fed it to her and she loves it. Now I discover DMB, and did the calculation. The phosphorous DMB of that food is .8, which is .2 above what I read is the recommended .3 - .6 My idea is to supplement every meal with a phosphorous binder, hoping to offset that extra .2. Since I'm so very new at this, is that good or faulty logic? Thanks for your input!
