I received an email from my friend saying that the emergency clinic vet did CPR on Osiris but he just couldn't bring him around. The vet says he still doesn't know for sure what took him but he thinks it could be feline leukemia. Shouldn't they be able to tell through bloodwork, etc? I've only experienced feline leuk once w/a rescue that I took in to a vet because it was clear that he had been badly injured, probably in a cat fight. After the vet tested him, I had him PTS. Now my friend has to worry about Malaya, her other kitten that she got at the same time as Osiris.
