On your first question, it sounds like your humidity is close, but a tad low for shed time. What are you keeping it at? 50 to 60 is a fine range, but during shed bump it to 70 or so. Did you give him a soak? Humid hides, or a lidded water dish with access hole in lid over heat pad can provide a sweet retreat.

Yeah, rats are noisy when it comes to being eaten. They can bite, too. Be careful feeding live, you'll feel terrible if Dante gets chewed up. I feed Xaero young rats now and I put them in a bag and smack against a door frame. They don't argue much after that.............
Lots of us feed f/k or f/t. It's not that hard to get them to switch and saves us lots of forehead slapping and expensive vet trips :cry:
