Using megestrol acetate (MA), a human drug used veterinary off-label as an estrus blocker in female cats, is a simple and safe way to buy more time for TNR programs to perform their role. Cheap and readily available, MA has been used for years in Europe and other parts of the world to slow the explosive growth of feral populations. Introduced to individual cats or colonies through once a week micro-dose ingestion in wet food, the synthetic hormone is simple to administer and safe to use for all cats that have reached the age that they may birth kittens.
With a relatively simple protocol to follow, this is a process that can make a significant impact on feral populations while ensuring a safe and effective way to slow or stop estrus cycles in female cats until trapping can occur.
