My kitty is very ill. Stopped eating a couple of days ago, today was the earliest I could get him into the vet. He has a bad heart murmur and is severely anemic, 8% red blood cell percentage of blood volume, normal for cats is 45-55%. They still do not know the cause, xrayed him and no fluid build up, organs look well defined and normal, no obvious tumors. Whatever it is he developed rapidly in the space of a couple of days. They gave him IV antibiotics on the chance an infection is bursting red blood cells and are doing further blood work. I should have the results tomorrow but they say there is a good chance he will not make it through the night.
