Merecedes and Mclaren have one of them, I managed to break the flap so they havent got one, but they would go thru it when they did have one. I have also used them for sand pits

and every rabbit used will go into go into it to have a play!
Only problem I have found is if i put too many woodshavings in there then they dig and push the woodshavings out of it.
