[CW: rapidly moving cat, the light may be blinking a little due to poor camera setup]
Ruh is laying on the penultimate shelf of her cat tree, with her back pews hatched into the pole, and playing with a cat toy hanging on an elastic string.
She's grasping the toy and a knot on the string with her forepaws and trying to bite the string (except she has no teeth). As the toy bounces back, she is repeatedly catching it with her paws and trying to bite it. Then she holds the toy in a paw, and tries to bite the string. She stops clasping the pole with her back paws, and moves to holding it with her fore paws instead, taking the toy with her. Then, back to the previous setup for a while, until she just stops biting and lies there, holding the toy for a while. Then she tries biting again, until finally she gets up and sits at the back of the shelf.
