Can your pet open doors?

My dad has a cat called Ralph. He's mainly white with tabby blotches, and he's sooo stupid we love him to bits but he's a total idiot.

He does this cute thing with a door that he wants to go through which is slightly ajar. Our other cats have always been able to hook their paws round the door and pull it open. Not Ralph! If the door is ajar, he puts both his paws on it, and pushes it shut. He's a big fat boy as well haha, so it properly clicks closed. And then he looks at you, like 'so? what now?'

Do other people's animals do this?!
