Renal failure (the link is to a site devoted to extensive information about feline chronic renal failure, but briefly discusses the acute type, as well) is quite common in cats.
Boots is thirteen, a bitty little thing - under nine pounds soaking wet - and is not a big eater. She heads out in the morning and deigns to come in around dusk (mostly). When she stayed in her bed two mornings in a row and didn't even ask to go out, I realized that something was up. For two days, she did not eat or drink, was very lethargic and seeming to go down hill quickly. Off to the vet where she was diagnosed with renal failure - the numbers from her blood work were extremely worrying. They kept her for IV hydration, but her prognosis was not good.
Smart vet we have! He started her on antibiotics in addition to the IV fluids, and she responded well enough to come home. But for four days, she hardly ate anything. She would eat three or four nuggets of food from my hand a few times a day. I give her the liquid form of the antibiotic twice a day - neither of us likes it very much.
It's been an emotional roller-coaster: she's eating; she's not eating; she seems better, then worse.
Fortunately, she has been drinking on her own and, finally, has started to eat her regular amount by herself. She loudly demands to go out several times a day and has started hanging out with the other two cats again.
It is impossible to know how long she will be with us; there is kidney damage, and she's no spring chicken. Still, we have her for now, and that's really all anyone can say about any life. These times remind us to appreciate and love what we have.
