I have to agree with everyone else. Sounds like you have a teenage bunny whose hormones have kicked in on your hands! I would definitely suggest not free-roaming. I had three babies and as their hormones kicked in, they were TERRRORS. As his hormones kick in he will most likely begin to lose his litter habits (sometimes not but usually it does) which could be a problem for your roommates too… so keeping him penned up may be the best solution for everyone until you get him neutered. You can have him neutered as soon as his jewels drop so you won’t have to wait very long at all most likely.
Although the squirt bottle trick can sometimes work, it usually doesnt in my experience. I think it’s turned into more of a game with my bunnies than anything else. It sends them flying across the room but they are usually back to doing whatever bad behavior they were before within a few minutes. Baby bunnies have VERY short attention spans in my experience so I would try and look through some of the older posts about home-made toys to keep his mind active and keep him busy. With my babies it was all about keeping them in check with LOTS to do. Things to jump up and scope the room around on, wooden sticks they could chew to pieces and throw around, paper towel rolls, toilet paper rolls cut in weird angles or filled with hay and a treat to keep them set on getting inside the paper roll, and towels! My brats LOVEDDD towels. They could do so much with them. They would toss them around, dig into them, drag them, and yank on them with their teeth. Cardboard boxes made into diggy boxes (cut a hole in two sides and fill the inside with something he can dig through like shredded paper). There’s a TON of different home-made toys so you can experiment without spending a ton of money. Another favorite is an old phonebook. Bunnies LOVE tearing them apart and the ink is soy-based so it’s safe.
Hope this helps a little
