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.
