Squirrel also works for him. Maybe even ermine or sugar glider.
(Hmm… Sugar glider, yes. Ermine or a ferret or weasel of some sort… possibly. Not too big on the squirrel, actually, but that’s really just me personally. It might work for Kaito, considering all the times I’ve seen them try stealing food from the bird feeders at my grandparent’s house. And more than one instance of jumping from a freakin’ tree to get past the barrier they put on the pole. But they all seem to be more high energy animals, which I actually don’t normally associate with Kaito. Playful animals I do, but Kaito really isn’t as active unless he’s got an audience. He’s really fairly quiet most of the time, just friendly.
(And I know these animals aren’t hyper all the time, and sugar gliders not really at all, but the general reputations of the other two precede them. Hence my ordering of likelihood going in backwards listed order from what you gave.))
