Yondu's doing his damndest to make his legs not TOO available. It makes him practically tap dance in slow motion while this 'cat' seems to want to leave its scent on him.

"That'n ain't a cat. That'n's a Flerken."

Now that it's on the floor he'll say that. But he finds the distinction very important. "You know how in the wild you might get two animals that kinda look alike? But one of 'em's normal and best it can do to hurt anybody is to give 'em a nip an' one of 'em got big ol' teeth and a pocket dimension in its belly where one can hold several grown adults? Sorta like that."
