No audio or video of it, sorry! And the times that he does it are so few and far in between, it's actually only happened twice (to my knowledge).
Everyone is getting along much better. It's been a good week. Zero loves to bop the dogs any chance he gets. They don't mind, and I find it to be so adorable.
Thanks, bluemilk. My dogs are really great. They are so sweet, and absolutely amazing with the kittens.
