Things that global warming is responsible for: Melting glaciers, skinny polar bears, disappearing coastlines, and rampant kitty sex.

That’s right. We’re seeing an increase in hot pussy action as global warming gets America’s cats all hot and bothered. Climate change is expanding the kitty mating season and creating — you guessed it — more baby kitties.

According to the group Pets Across America, there was a 30 percent increase [PDF] in the number of cats and kittens coming into some of their shelters from 2005 to 2006, while the organization saw a 7 percent increase overall. Other shelters across the country have noted a similar increase.

“Cats are typically warm-weather, spring-time breeders,” said the group’s president, Kathy Warnick. “However, states that typically experience primarily longer and colder winters are now seeing shorter, warmer winters, leading to year-round breeding.”

Thanks to warmer weather, there’s no longer a lull in breeding season. So cats are breeding all willy-nilly, all the time. Perhaps this could be a boon for the biofuels industry.

Since Bob Barker retired this week, I’m here to remind you to help control the pet population: spay and neuter your pet today. And quit warming the planet already.
