Our cat has been vomiting frequently (almost daily) and would not eat. We took him to the vet and blood test showed a white cell count of ~ 35,000. He is 15+ years old and has always been inside the house and had been totally healthy until about 1 or 2 months ago.
Could he have Feline Leukaemia Virus? I have observed traces of fresh blood in his vomits 2 or 3 times.
