Katy Perry and one of the Popcats are part of the Top 10 video CATdown for Adopt a cat month.

I know June is basically over but it’s still Adopt a Shelter Cat month. To inspire cat adoption, our pals at the ASPCA are teaming up with celebrities like Katy Perry to host the Top Ten Catdown on Ustreatm.tv tonight at 7 p.m. You can watch it right here. (Just scroll down to see the player.)

Think MTV classic video countdown shows of the 90’s but with cats! During the broadcast, the ASPCA will countdown the funniest and most adorable cat videos, bring interviews and spread the message of how important it is to rescue and adopt millions of cats without homes.

There will also be a trivia Twitter party happening along with the live stream. Use the hashtag #CATdown. The party will feature questions about famous cats in pop culture, with a grand prize being a year’s supply of Fresh Step cat litter.
