Professor Pussycat is happy explain gravity to you, and other types of physics that you use in everyday life (if you are a cat). That doesn't mean Professor Pussycat isn't a typical cat who thinks you're an idiot for even asking. Cats are like that. The "why" question doesn't even deserve an answer. It's because he's a cat. This comic is from Einstein's Mama. There may still be a way to stop cats from knocking things onto the floor, if you are so inclined. -via Geeks Are Sexy
