The Humane Society of the United States estimates that approximately four to six million cats and dogs are euthanized each year in the United States because there are not enough homes to adopt them all.

Spay or neuter your own pets and encourage others to do the same.

Educate yourself about the benefits of spaying and neutering, and about the myths, so you can speak intelligently on the subject.   Spread the word, and support organizations that encourage spaying and neutering.
