Just a bit of cuddling. Or, well. Mordecai, the owl, likes having a nice full belly, while Ploro, the mouse, enjoys cuddling atop/with full bellies. So the two have a nice bit of friendship going on. And Ploro feeds a lot of friends to the owl.

Anyway, really lovely sketch from sharpt00th. They're great.
And Ploro is a mouse character of xionzappa2's. :3
