Powder is fine ON the bed, but this morning he lost his under the bed privileges – he chewed a hole in the box springs, jumped inside and refused to come out. He would come to the hole and look at me like, then hop away like “ha ha, can’t get me here!”. He woke me up doing this, so I had to get up with like 30 seconds awake, take the entire bed apart, remove the mattress, lift up the box spring and pull him out since the bed isn’t tall enough to crawl under. 6 months sleeping under the bed, he just decided to be a bad bunny about it. Then he preceded to spend 20 minutes running from me, when I was trying to evict him from my bedroom… he just wants to see how far my patience lasts today I swear lol he’s lucky he is cute 
My bed is short, he can just barely stand up under it (6lb bunny) . What would be the best things to use to block it off? Boxes are too tall and NIC panels he’d grab and knock over if they weren’t secured to the bed frame. What do you guys use? Or suggest. He’s an expert pusher and for something to be heavy enough, it has to weigh a few lbs or he just shoves it out of the way.
