So, I’m adopting a new bunny saturday, a Holland lop. It’s an adult and it’s medium sized but that’s all I know about it (the website says it’s a boy but the woman I contacted used ‘her’, so I don’t know it’s gender…). It looks like this:

If it’s a boy, he’ll be Mufasa, and if it’s a girl, she’ll be Rose.
I’d be keeping it in my room, but since my walls are all really small (my room is in the shape of a pentagon, so the longest wall is needed for my bed), I was thinking of doing a taller cage, like a dog kennel and making it so it was comfortable for the rabbit.
What I’m wondering, is how big is a medium sized Holland lop? Would a dog kennel be big enough for it?
Me and my mom went out shopping today and we got paper pellets for litter and crumbled paper bedding to line the bottom of the cage with, and we also got timothy hay and pellets for eating. The sanctuary we’re adopting from has starter kits that hopefully have other things we need to keep the bunny happy.
Another question I had was about bunny-proofing my room.
I’ve got a lot of wires in my room (for lamps and hair dryers and chargers and the like). I also don’t want it crawling under my bed, and my desk is wooden. So I was wondering what I can do to keep it from a) chewing up my desk and chords and b) crawling under my bed where I can’t get it and then chewing up the carpet or my bed.
Is there anything else I should be doing? Anything I should know?
Thanks!
