The rats are a newish thing, and I bet they can work out something along the lines of "only three, small, well-behaved, and they *don't* sleep in the bed", if only because from what I can tell, Piper without *any* connections to people goes totally off the rails, and given the power he apparently has, that is not a good thing. I mean, it's not like Booster doesn't go off the rails *too*, but he's never blown up a planet in reaction.

I suppose Piper/Starman depends on how much snark Starman can tolerate, and how Piper feels about aliens and dating bisexuals...

yes, for Christmas.
