If you'll recall, Monica, my RB Puddy lived w/CRF for years and was on subQ's in the beginning twice a day and after she had one kidney removed, she even went off subQ's for a while. Your vet says that Mr. Kiki's kidneys are small? Well, Puddy lived w/only one kidney for quite some time and that one had nephritis and was the size of a pea instead of a kidney bean as it should have been. So try not to take a fatalistic outlook about this. Mr. Kiki could have lots of time left yet. How old is he?
