I'm from Nova Scotia too
I just got a Flemish Giant a few weeks ago. He has the whole kitchen to himself. everything else was too small. He is such a beautiful boy, in temperament as much as in looks. He is very very cuddly, very needy and demands a lot of attention which he gets in spades.
He couldn't stand any close enclosures and the kitchen is a high traffic area so he gets a lot of attention. Both my bunnies run more than 6 hours a day out of their enclosures.
I'd have them both out all the time because I'm not a believer in cages but until they are fixed, it has to be.
Good luck with whatever decision you make. The spare room sounds like a wonderful idea.
