He went to the vet today and she did a check up and de-worming. He looks great! She gave me a tip to go ahead and move him to the big cage (the double "rabbit cage" I raised Percy and Juno when they first came home). I made one side with milk in a dish and litter in a pan. The other side has his bed and toys. He is in 7th heaven in there!!
ETA: I went to take some pics of him in there and he was CLIMBING to the top of his little sisal post!!! LOL He is so stinkin cute!
