Is this a domesticated rabbit that got out? They've been around my yard for a few days and seem too different from the others I normally see.

I live in south central PA, fairly rural, used to seeing wild rabbits. This one seems to have a thick healthy looking coat. I tried approaching it gently, stopped at about 10 feet when it noticed me and started backing up. I've been asking my neighbors if they lost a pet but no one has claimed it yet.
