Spontaneous firing of an axon resulting in a visible twitch of all the muscle fibers it contacts; indicative of denervation.

feline immunodeficiency virus (FIV)

A retrovirus that infects cats; similar to human immunodeficiency virus (HIV, the virus that causes AIDS), it attacks the immune system and as a result, the cat is more susceptible to infections that do not typically affect healthy cats.

feline infectious peritonitis (FIP)

Highly contagious disease affecting cats caused by a coronavirus (so called because of the crown or halo appearance under a microscope).  Peritonitis is inflammation of the peritoneum.  The virus is shed through saliva and feces.

Related Words

feline leukemia virus (FeLV)

A retrovirus that infects cats and usually transmitted through saliva or nasal secretions.  It can cause immune-mediated diseases, leukemia, lymphoma and anemia.
