[Gremlins]How should I care for a Mogwai in space?

My pet Mogwai managed to stow away with me on my trip up to the International Space Station. I realize there's an obvious solution, but I'd really rather not throw the little guy out of an airlock. So how can I take care of him until the next shuttle heads back to earth in about a month?

He's very well behaved, so keeping him away from the few sources of water shouldn't be much of an issue, but will the station's UV shielding be enough to protect him from sunlight? And when can I feed him, given that we have a sunrise every 90 minutes up here? And are there any other concerns I should be aware of, or special precautions I should take?

Regarding Midnight, in space the closest approximation would be when you're directly opposite the sun on the other side of the Earth, halfway through your transit through the Earth's shadow. The safest play is going to be to simply not feed the little guy when you don't have full line of sight on the sun. 

As for solar exposure, don't assume that the windows are going to be enough; they're thicker than on Earth but you're also getting blasted without the benefit of an atmosphere. Set up a section on the ship to be the Mogwai's home, either without windows or with the windows physically blocked.

As for water... assume nothing. Jackassing around with floating water is a very popular thing in space, both for personal amusement and to demonstrate low-gravity on video for the folks back home. Make sure the rest of the crew knows the score, *especially* the potential consequences of fucking up; "what's the worst that could happen" could be the sentence that get you all killed.
