Funny behavior

I'm a cat person.  I'm not a cat lady I only have 2 cats though so don't worry.  I love dogs but I think cat are hilarious sometimes!  I swear they are so intelligent.  They know exactly what they are doing.  I had a cat in college that every time I would shut the door to my room, which meant I was shutting him out, he would stick his paw under the door and shake hard till I opened it up for him..
