Feline distemper

Feline panleukopenia virus (FPV), also known as Feline infectious enteritis, Feline parvoviral enteritis, feline ataxia, feline distemper, or cat plague, is a viral infection affecting cats, both domesticated and wild feline species. It is caused by feline parvovirus, a close relative of both type 2 canine parvovirus and mink enteritis. Once contracted, it is highly contagious and can be fatal to the affected cat. The name panleukopenia comes from the low white blood cell count (leucocytes) exhibited by affected animals.
