He's lovely. Is he bonded to Star?
Runaround tunnels are fantastic! It does work without buying the Runaround doors. The run that Rupert and Star have has two sliding doors which are the perfect size for the Runaround tunnels. The sliding door keeps the tunnel in place and they do not escape. Also the tunnels have ridges that keep it in place too. My dad has also cut a tunnel size door on the run which the tunnel goes though and it seems to work!Aw lovely Rupert
I'm going to be getting some Runaround tunnels soon, to connect my hutch/run and my new run. Have you found they work quite well without the need for the doors? as I might be able to save some money if I don't have to get those too x
