Birth Control For Cats Using FeralStat

English: Portrait of a female feral cat (Felis...Image via WikipediaWhat happened to FeralStat? It was being used successfully by many people who care about humanely controlling feral and stray cat populations. Of special note is that one person could handle a fairly large colony of cats without help or great expense.

By contrast, it's virtualy impossible to trap, transport, and pay for very many cats without the help and cooperation of other volunteers and at least one veterinarian.

We need to contact veterinarians and pharmaceutical companies to re-release the drugs that were available for more than 30 years.

(Some of the information for this article is from

Here is some information to help in this quest:

Name of drug: Megestrol Acetate (Feral Stat)
Email: info @ (They are collecting reports from people in the field who have experience using Feral Stat and want to hear how it has helped them in controlling stray and feral populations. Only send useful information; do not write to complain or ask about something.)

If enough people raise the issue, perhaps we can help each other help more cats.

Thank you for posting the link about an alternative to Feralstat! That thread is very interesting and informative on the use of megestrol acetate.

After reading your link for Feralstat, I searched more and found a very informative thread at Topix that you should really post about to help out feral cat colony caretakers. Read the posts to the end and one can see correct dosages to give to the colonies:

I think the linbk is for the last page, but if you start at the first of the thread and read through, you'll find it is a very helpful topic to help out other caretakers.

Thanks for your comments and also for the link to that forum on the subject. That page should be printed off and kept handy, as it's very very informative on relevant issues when caring for any cats, but especially strays or ferals we may be working with.
I'm getting emails from others, too, who used to manage feral colonies with FeralStat and are no longer able to obtain it. I hope this situation improves soon, as many individuals, typically without major resources, are unable to afford or even accomplish the much more difficult task of capture, transport, and then after care for neuter/spay surgery. Handling ferals one at a time like that is pretty close to impossible. That's why the chemical approach can be so much more effective, allowing individuals the ability to care for larger groups, by themselves.

I've been trying to find ferastat and couldn't and I found your site with that informative thread about using megstrol acetate instead of feralstst. that thread has saved my life! thank you for posting it. I hope other rescuers can find that thread too.
