We have a male cat about 11 months old, and he has two bare patches on his back legs. They aren't red, or scabby, and he doesn't pick at them at all, they are just there. Wondering what it might be. They have been there for a few months, and haven't really changed at all.
We have lots of hardwood floors, and when we're playing, he'll slide around a lot, but from watching him, it doesn't seem like he slides on that part of his feet/legs.
