Answer
Terry,

This question was originally answered on January 18, 2010,  Here is my answer:

"However, these are hormone therapies and should always be used in conjunction with a vet. A better approach is to join a group, like the Alley Cat Allies and have these cats trapped, tested, neuters/spayed, vaccinated and released. Spaying and neutering is the only sure fire birth control method. Also, cats that are spayed and neutered will keep whole cats out of their colony!!!!! The problem with feeding a colony of cats is how would you determine they were getting the right dosage of anything you were going to try to give them.
