Well, they havegrass mats and a couple foot pads, but no, they've never had a problemwith sore hocks. Most of the breeders I know, and many pet owners, keeptheir rabbits on wire floors, and they rarely have problems with sorehocks. It's not something that is solely caused by wire flooring.
Unfortunately, wire flooring gets a bad rap. I use it because while myrabbits have impeccable manners outside their cage, inside theytreat it like one giant litterbox. They're seniors and pretty set intheir habits. Because of that, wire flooring is much cleaner, much moresanitary, and much healthier for them.
They do get to spend time outside the cage, so it's not like they're in contact with wire 24/7 either.
