I also use Carefresh. It works well, but if I could find a local source for Woody Pet I would use it instead.
As for pellets, make sure you get just plain ones.Don't get the stuff with treats mixed in. Young bunnies(under 6 months old) should have alfalfa pellets. After that,you can switch them to timothy-based pellets, which have less protein,usually more fiber, and less calcium. Whatever youget, try to go for high fiber. I have personally had problemswith feeding average-to-low fiber pellets, which are the types you findmost in pet stores. And don't forget the hay!
