I made some observation on all the bunnies’ behavior while using the run. Most of them like to dig at the 4 corners and causes all the wood shavings to go flying out the play pen. I have since placed a corner litter tray at one of the corners. I then place tiles on the other 3 corners. The tiles worked out very well. I put cardboard boxes on top of 2 of the tiles and guess what?
They love chilling out on top of the cooling tiles!
