NO MORE KITTEN SEASON.ORG

Already In Use
During COVID, it was difficult to find a non-emergency appointment, at a vet office. Spay and neuter surgeries were put off for months.
It was then announced, by several national organizations, that Megestrol Acetate (MA) is a safe, effective contraceptive that could be used to prevent new pregnancies, while spay/neuter surgeries were unavailable:
Maddie's Fund ---- Alley Cat Allies ---- Alliance for Contraception in Cats and Dogs
Others started supporting the use of Megestrol Acetate (MA) during COVID, or have already been using it, for up to fifteen years:
Fairchild Foundation (in PA)
Columbia Animal Shelter (in PA)
Little Woman Home Rescue, (treating street cats, in Galveston, TX)
Toronto Humane Society
Birth Control for Cats, site owner and followers
Breeders of fancy cats, who carefully schedule and delay the matings of their valuable females
Many other colony keepers, who started using it in 2008, with the name "Feralstat"
