For some reason my cat likes to attack me if i breathe in and out really quickly. He starts to breathe in and out quickly too and the next thing you know he's noming on my arm.

To prevent serious injuries I have to use my sweater, double layered. Even still his teeth get through and scratches up my skin.

Back in the day I would play with him like that with my bare hands. If i tried that now I'd be in so much pain. His jaws are too powerful for that now.
