At what age should you spay a kitten?

Kittens can be spayed or neutered as early as eight weeks old, states the ASPCA. It is advised that it is done before the cat reaches the age of five months to avoid the risk of pregnancy or urine spraying.

Older cats can still be spayed or neutered; however they should be first examined by a vet to ensure their safety. Females in heat may risk increased blood loss. Spaying and neutering is vital to ensure that the cat doesn't contribute to feral feline overpopulation. It also has a variety of health benefits, including a reduced risk of certain forms of cancer, states the ASPCA.
