At Last! An Oral Contraceptive for Cats.

As anyone trying to curb the growth of a feral cat colony knows, it is often difficult—if not impossible—to trap every cat for spay/neuter surgery before it reproduces.

Now FeralStat, a feline oral contraceptive, is aiding in the management of feral cat colonies worldwide.

FeralStat is a synthetic progestin that prevents female cats from coming into heat. The active ingredient in FeralStat was patented and FDA-approved in the early 1950s. It is used extensively in human medicine, and has been prescribed by veterinarians for over 30 years for cats with skin, urinary tract, and behavioral disorders. It also has FDA approval for extra-label use as a feline oral contraceptive to postpone estrus in cats.

FeralStat is intended for use as a complement to spay/neuter and Trap, Neuter, and Return (TNR) programs for feral cats. To administer, simply mix FeralStat with wet cat food once per week and feed to all the cats in the colony.

Although it is designed for female cats, FeralStat has been given to male cats, pregnant females, and kittens who are sharing the food supply with no report of negative side effects. That is because a miniscule dose does the trick.

A cat's minimum effective daily dosage of FeralStat is approximately 0.04 milligrams—which is smaller than a grain of sand. In contrast, the daily dosage of this same compound, when used for treatment of tumors in humans, is two teaspoons or 20,000 times the amount.

FeralStat was developed with the assistance of veterinarians, research pharmacologists, chemists, compounding pharmacists and feral cat caretakers.

FeralStat is recommended to curb the growth of feral colonies in places where there is limited access to sterilization services or too many cats for TNR to be effective.

FeralStat is available by prescription only. For information on obtaining a FeralStat prescription, call 860-399-0097 or e-mail info@feralstat.com (inquiries must include a contact telephone number for follow up).
