I’m not recommending you actually try this, but on rare occasions, cats and mice can be friends. Yeah, if I tried it, I’d wind up with half a mouse. But cats and mice are both extremely intelligent and highly adaptable, and can do things you don’t expect. I am assuming the animals in these videos remained friends off-camera.
I once had a mouse who liked to groom my mustache. Think about that. What did she see when she saw me, besides a mustache that needed grooming? But mice do learn to relate to you on a personal level, and I’m blamed if I can fathom how that happens.
