Best Friends Animal Society, an organization for homeless animals started a campaign called “Prevent more. Fix at Month Four” to educate owners on pet birth control: spaying and neutering.

“We are hoping to maintain long-term traction by shifting the mindset of our country,” she also added. “It will become commonplace to fix your pet at four months, reducing the number of pets that enter, and ultimately never leave our shelters. ”
