Thanks. I had seen that one.
I really need one with a door at ground level, nothing for him to jump/hop over, as we've had to cover the edge/lip of this crate as he's doesn't hop in very well he's tried and has managed to get one of this back paws trapped. Also given the opportunity he wouldn't think twice about jump over, which he's not meant to be doing.
I'll need to find something that's easily portable, so I can move to from house to garden on my own etc. I have had a look at baby play pens on ebay, but they're a little small.
