When I first got mine, I read that I shouldn't "over handle" them as it stressed them out so I don't pet them near as much as I'd like to.
They seem to love being out and getting 'back rubs' so if they're not freaking out or 'going off their feed' because I'm handling them, it's okay to take them out more often?
All of them apparently enjoy being out and cuddled enough that they don't seem to want to 'go home' and 'argue' with me when I put them back.
On the days I don't take them out, they look like they're sulking.
[they come out of their hides, try to get my attention and then go back in their hides and "mope"]
I strictly observe the no-handling-after-feeding rule, though.
Well how much do you handle them now? I handle mine at least once a day for at least 15 20 min at a time, he seems to enjoy the time out and is still on his eating schedule
