And by kid, I mean kid Chinchilla.
Seriously, I used to LOVE playing blanket cave when I was little... for those who lived deprived childhoods (or those who are entertained by xbox and tv instead of inventing games to entertain themselves), that's a game where you drape a blanket over yourself and pretend it's a cave.
Anyhow, this is a great way to spend bonding time in close contact, without any restraining... I lie down on my bed, drape my blanket over myself, and stick up a knee and prop up my arm to turn it into a cave. My chin's rodent instincts kick in, and he goes "A CAVE! I shall explore this mysterious cavern!" and he can spend a good long while going in and out and exploring it, climbing all over me in the process.
I don't even have to coerce him or anything, I prepare the cave entrance and he will notice it eventually and decide to go exploring.
Those who have had to deal with chinchilla proofing the undersides of sofas and beds and such will know the "magical allure, magnetism, and compulsion" that cavelike things have over chins.... lol...
