You sure the bunnies didn’t knock it down? Mine go mental at night and throw everything. We call it a rabbit partyI think something tried to attack one of my rabbits last night, Rabbit is fine, I have a cage under their cages that keeps predators from having access to the bottom, and they can move to the middle of the cage to go untouched from predators. I found the feeder and water bottle knocked off one of the cages. Rabbit was just fine, he was hopping around normally, no panic. Seemed happier than usual even. But I had to put the feeder and water bottle back up. The Rabbit Pen is near completion. I can only really put one rabbit in the pen at a time but I can hang a cage in the pen so no predators can access the cage.

There could’ve been a predator though... do you have a game cam? Set one up and check it out.
