I have a 3yr old cat and both my puppies play and wrestle around with her, we supervise it thought because it can get a little rough and one of my puppies will get hurt, but they're always the ones that start it. I truly think they all love each other and don't mean to hurt one another, their just playing. It also helps that there all about the same size, give or that a few lbs. I don't have tiny ones, 6lbs and 10.5lbs the cat is 9lbs and fully clawed. When the cat has had enough she jump up on something where the dogs can't reach her. Welcome to YT you will learn alot here!!
