It may be hard to convince them, but try to get them around your bp. My roommate was iffy about having our bp's in the house and said we had to have them in our room and she just doesn't want it to get out and eat our dog [a 45lbs. Husky]. After giving her facts [bp's only get to 6 feet as an absolute max but normally between 4-5 feet and they only eat rats and one of ours doesn't even eat live] she calmed down about them getting out and eating the dog, but she was still scared they would get out of their tanks and end up in bed with her. BUT once we got all the snakes settled after the move, we took them out and she warmed up to them. She loves our female bp now.

As for the frozen mice, you can get a small freezer and fridge and keep it just in your room and keep them there. I've seen a few at like Sam's Club for max $300 and that was for a good size one. If there's a Sam's or Costco type of thing around you might find a good deal there. Especially now while people are moving into dorms and things and need things like that. Bed Bath and Beyond might have one, ummm Home Depot or Lowe's might have some too.

Best of luck!
