We had a cat a few years ago, that came to us as a kitten when we had two dogs in the house already. She forever thought that she was a dog, and apart from cuddling up to them in their beds, she used to steal their bones off them, by butting in and then wouldn't let them have them back. She would also walk out with us, which could be a nuisance, and usually ended up having to take her home, and start again, hopefully before she came through the cat flap at full speed, looking for her 'boys'.
I used to run a small dog grooming business from home and she was always jumping onto the table with some startled dog, but they all seemed to tolerate her well, and all the neighbourhood dogs got met by her.
