he eagerly springs out the door when I say "out" and back in when I say "in". he doesn't have to be walked for half an hour before peeing any more either. I let him into the living room for a little while and he was respectful of (but politely curious about) Bruce and Ninj. (they're not sure about him - and dogs and cats have really different ways of playing - but it's pretty clear they'd eventually work it out.) with his super gentle temperament (and some basic training) I'm sure he'd be able to do really well with other animals or children.
we also worked on "sit" for a while and he seems to be figuring it out. (the cats donated some of their greenie stash towards this project. thanks, cats.)
in short, Poqs is doing GREAT and he is going to be an awesome pet for his new family! (and I must admit I'm looking forward to going back to just having cats - dogs are really labor intensive!)
