Terminating pregnancy in dogs and cats

The termination of canine and feline pregnancies might substantially reduce pet overpopulation in the United States. As many as four million pregnancies could be annually terminated to prevent the births of millions of puppies and kittens destined to be surrendered or abandoned. While ovariohysterectomy can be performed safely in most pregnant dogs and cats, the development and utilization of non-surgical abortifacients has been slow. Abortifacients which are highly effiacious, safe, and reasonably priced continue to be sought.
