For what cats?

Three cats are in a room with tiled floors and walls; one dark-colored cat sits facing away from the camera, while a tabby cat lies on its side in the foreground and another tabby cat stands in the background near a scratching post. The tabby cat in the foreground repeatedly extends its hind leg to bat at the dark cat, which remains seated and turns its head slightly in response, while the third cat watches from the background.
