Susan is out and about, trying to get the lay of the land, which in his case means "climbing all the trees". He's been a cat before, a lot of times, but never a cat that can climb trees as easily as this, that can scale them without a thought, and it's fun.

Of course that also means that he sees the little bat attempting to climb, and he looks down at her and cocks his head as he looks up to the next branch.

"Can't you just fly to it? With your wings."
