Hi, @dswigle. Thanks for everything: the nice comment, the upvote, and the tip! :-)
When I got the first shot, I was sure that's all I'd be able to get, knowing how they'd reacted before. I was happy when I saw that the kittens were coming back and got comfortable enough to just roam around and play as if I wasn't there.

Happy belated Caturday! And have a wonderful Sunday, too! :-)
