A little carper isn't bad. Just make sure they have hay and other nutritional stuff to eat, too. As for the baseboards - blobk them off. We have some white shelving that we used to block off Miss Hoppy's access to the baseboards for a time. It's funny, some sge never touched, while others we finally gave up and let her nibble - we just tell anyone who asks that that's a bunny-beveled edge. A little sanding and a little paint and no one would be the wiser!
