World Spay Day is an annual campaign of The HSUS and Humane Society International. Every February, we shine a spotlight on spay/neuter as a way to save the lives of companion animals, community (feral and stray) cats, and street dogs who might otherwise be put down in shelters or killed on the street.


Make Every Day Spay Day!

Don't wait for the last Tuesday in February to celebrate World Spay Day. When you spay or neuter your pet, you make your pet healther and you make life easier for the both of you. You also help solve the tragic problem of pet overpopulation. Take the first step today:
