Nice!
If I have any left after this weekend, I'm going to switch them over to one-on-one. Won't probably go whistle yet, most buyers are just looking for pets, but I'll stop and start a lot. (I probably should go ahead and do it with the group, but it's such a frenzy!)
Here's a video of 7 of the boys by themselves, Sit/hold/come to affection (no food.)
