To be respectful to your roommates, you might consider identifying his exercise area early on. When I lived alone I let my bunny run around the house free, but when I got a roommate, I confined his roaming space to my bedroom only so my roommate doesn’t have to stress about leaving her computer cord out etc. It might be something to consider discussing with them. I made the decision to keep him confined, even though my roommate wouldn’t mind if he ran loose- I just don’t have the cash to replace her stuff if he gnaws her wicker chair/computer cord etc lolol
Additionally, I would change the litter frequently- I change mine every other day. Offensive pet smells can be a point of tension, so if it’s your pet, it’s considerate to make sure the cage/litter is kept really clean to keep on good terms with your roommates
Don’t let your roommates just pick him up right off the bat! Let them just hang our with your bun and feed him herbs to get to know your roommates the friendly way <3
Have fun!
