Yes, a taller cage would be better for him as he loves to periscope as well. I just need to see tomorrow how I will fit it in if I get it. I got a really short video of him escaping tonight...he is just such a chancer, when he gets his opportunity, off he goes lol.
Denise, it is sometimes difficult to judge size when you see them on their own on the floor. Í always like to see buns with people as it´s much easier to see how big they are. My sis was amazed how big Monty is when you saw here with missy....I hadn´t realised how big she was so I´m assuming Thumper is similar and that is big. In comparison to mine, they´re enormous, mine are really, Bandy is a little bit bigger but it´s mostly fur. I do love the big flemmies though although I think they´d be a bit too big for my place.
