Yep, he's in quarantine. I hadn't thought about the rats being bad to give Jacks, so thanks for the (duh!) reminder there...! I always just freeze the ones that Jackson doesn't eat- sometimes I'll offer two if they're smaller than his usual size and he'll refuse seconds.
I'll give him another week and try to feed live on Monday- before going to work at 2am.
I'm not concerned about his feeding response so far, I know he's in a new place and moving around stresses me out, too!
