Booth (8 mo. b/w kitten) was helping me test Oreo around cats...she's rather interested when they're moving...if they're sitting still, lying around, she'll just nuzzle them and walk away. Moving is definitely more interesting to her. She's still being tethered, as I don't trust her at all yet. You can also see all of the other dogs around her...she is dog friendly (tolerant)...but isn't a big player.
(and yeah, you can see Booth offering his new behavior: "beg")
