Aww thanks!
He used to have a tube behind the sofa but since giving him the other side of the room, he has the big tube just in his pen now
He runs up, down, sideways... sometimes he tries to stand ON the tube!!!
Runaround, I did try and use some I found with roadworks but they are smooth inside and therefore unsuitable.
I went up to Cheshire when visiting my Gran and asked for specific lengths which they happily did for me! I love that he has that extra dimension with the tube and his favourite place to be is on top of his litter box which has a carpet sample on top, he slid off of the top too many times hehe
