Pedro growls at us if we disturb him in bed...If one of us turns over and makes him move, he snarls and jumps down and finishes out the night in his dog bed, right beside our bed - a very plush one with a very plush blanket! He doesn't bite, but it sounds like he might when he growls.
My two Chis sleep well in the cage together, but neither would do well alone, so unfortunately, I have no advice on that one...Other than to make it as comfy and inviting as you can, and you might cover it with a blanket or something to make him feel safe!
