As previously posted, Probert can be a maniac in his crate. Sometimes when I come home, I will find that during the day Probert has moved his crate across the room next to Wrigley. He did this a few days ago, I moved him back, and the next day he was over by Wrigley again, so we've left him there. I am trying to think of a new crate arrangement in the bedroom since Wrigley and Probert seem to like being together.
Here is a picture of the previous crate arrangement and the one with Probert's changes (please excuse Maizy's breakfast in the second one, which she's flung all over the floor).
Don't ask me exactly how he does it because I don't know, but they seem to be happy with the new arrangement.
