Rabbit Tunnels from Newspaper. A must for every rabbit with time on their hands.

Rabbit Tunnels - paper and cardboard. Great for playing, hiding, chewing and digging

Play area using flexible corrugated plastic drain pipes. Pretty cool, though I'd be scared of cats and such hiding in there...

I have pinned a similar idea but this looks like such a great play ground and hiding space: corrugated plastic pipe play area for rabbits.

Underground hide-away for rabbits. Could make the top open for safety/easy access to clean

Rückwand in etwa so, viele Versteckmöglichkeiten, Tunnel und Heuraufen

Very cool playroom setup for small pets. My chinchillas would love all the hideouts and multiple levels.
