An adult kangaroo inside a house would destroy it. They can grow to 7 feet tall and 200-210 pounds. Not house pets. Besides, they're not tame and don't like people. This little fella was cute though, and seemed happy enough; He's lucky to be alive really.
I think the animal rehab group would have a lot to blog about, all those cute little animals they see each week. I should've mentioned hive, you're right.
