Two PETA members took to the streets of San Francisco today holding signs that read, "Condoms Won't Work: Fix Your Cat!" or dog. To drive home the point, as only PETA can, they were dressed as condoms—one pink and one blue. And the point they were making? The only way to get a handle on the cat and dog overpopulation crisis is always to have your animals spayed or neutered. 

"If cats and dogs could wear condoms, millions of animals would be spared from suffering and death," says PETA campaigner Katie Arth. "But they can't—so it's up to their guardians to take responsibility for spaying and neutering."

Six to 8 million unwanted cats and dogs enter animal shelters every year in the U.S., and roughly half of them are euthanized, according to PETA, because there simply aren't enough good homes for them. Millions more never make it to an animal shelter and are left to fend for themselves on the streets, where they often are subjected to cruelty; suffer from starvation, disease, or injuries; or are struck by cars. The solution is simple: Always spay or neuter your animal companions. Just one unaltered female cat can lead to 370,000 feline descendants in only seven years!
