Can your pet open doors?

I've got a cat that tries to open doors but she hasn't managed to get the hang of it yet. Over the months she's obviously noticed how we open the doors in the house and she tries to do the same by jumping up and trying to pull the handle but it never actually opens for her.

In a way I'm glad because otherwise we'd be sat in the house freezing cold with all the doors that she's opened wide, because she never likes to stay in one room for too long!
