Natural Birth Control for Cats

Reader Question

You mentioned unwanted sexual behavior can be controlled by natural products (in addition to behavior control).

Can you tell us about these anti-estrus products?

Suggestion from our Vet


I am unaware of any “natural” products that safely and effectively act as birth control in cats.

Perhaps you are referring to the drug megestrol acetate (MA)? MA is a synthetic version of the hormone progesterone. Its use in cats is controversial. The drug has been used to control reproduction in feral cat colonies, but individuals given MA are at much higher than normal risk for diabetes mellitus and acromegaly.
