That's hilarious, about the strange cat.

I'm also cracking up about the cat who can't be bothered to open the dog door! lol. My black cat sits inside the dog door and waits for the dogs to open it and then slaps them on the nose. As a result, the dogs quite frequently can't tell if the cat is there so they'll sit outside and whine until we go in the kitchen and tell them it's okay to come in. Might as well not even have the dog door!
