He is doing just fine.  We went outside and then I fed him his dinner.  I did notice that the callous on his right front leg is bleeding slightly.  I dabbed it with a wet paper towel just a little bit.  It doesn't seem to be bothering him.  I went to the sink to re-wet the towel and when I'd come back he was already under the bed so I couldn't get to it anymore.  I opted not to crawl under the bed :)
