Hey everyone, it's been a while since i was here last.. i'm hoping i can get some advise. I have a friend whose cat has just been diagnosed with kidney failure. My heart is absolutely broken for him, Dizzy is only about 5 yrs old. He's always had bladder problems in where he was peeing a bit of blood from time to time, but the vets shrugged it off as a bladder infection & recommended different foods. Dizzy would get better, but then would lapse again and have blood in his pee. Recently he started throwing up and lost a lot of weight. YEsterday he lost his appetite altogether and would barely eat anything. When he would - he would throw up eventually. Even yesterday when they took him to the vet, they shrugged it off as maybe a reaction to some antibiotics they had him on for about a week. When he still wasn't eating today, they took him to the vet, where they sent a blood sample to the VEt College here. They found hi amounts of potassium in his blood.. and they said that the only options were to a) put Dizzy down, or b) do further tests for a "rare disease".. which would involve steroids. They didn't say what the disease was. Have any of you heard of such a thing? They are now stuck making the impossible decision of putting their best friend to sleep. I've been balling my eyes out for Dizzy since they told me.. I just can't imagine having to make this decision. I"ve offered to help pay for any further tests if they wish to persue.. they are such good friends, and dizzy is like one of my own kitties... need advice!!!
