I have 5 bunnies indoor. They have their own rooms. No cages. Recently, they have been kicking the litter and hay out of the pan. I thought maybe it was the hay (bought a new brand) so I switched back. Still happening. Everyday I walk into a hot mess of litter, hay and poop on the floor. I bought new high side litter pans still a mess. I used very little litter as well thus changing more frequently. Tried not using paper litter and only hay. HELLLLLPPPPP!
