I'm bringing my cat to the vet to get her fixed and to get her rabies and
Distemprement shots and I'm just wondering what the Distemprement shot is and what it does?

Distemper shots in cats are usually a combination called FVRCP.
FVR= Feline Viral Rhinotracheitis
C = Calicivirus
Both are highly contagious upper respiratory diseases.
P = Panleukopenia, which is considered distemper. It is very similar to parvovirus in dogs. It is HIGHLY contagious and VERY deadly.

Please note that if your cat has never had shots before, she may need to be boostered for the distemper shots.
