When I hold Snickets, she's constantly on the move. She's as bad as a toddler. The only time she's pretty calm is when I take her in the bathroom where we have heating lights, and there are times I put those on to get a better look at her (this was when I had to assist her to shed). But if I sit down it's go go go!
The one thing that I've noticed works, I'll put her down on my bed and fold my comforter over and she'll hide under there and kinda explore. Or, I have extra hides that she never uses unless I put her on my desk and put the hide out. She'll crawl in the hide and just sit there.
