thanks all in the end i brought this
they luvvv it it gives them so much more room to play and they both fit inside to snuggle on an evening....i was leaving the bunnies to have 24/7 access to there run but last night hubby caught 2 large foxes in the garden having a nose at my babies so even thought i dont think they'd get in i am shutting them up from now on just to be safe
