My female normal that I rescued from a bad home a year or two ago will not touch live prey. I've tried mice, rats, and just for kicks, ASFs (not trying to switch her to live, just out of curiosity). She does not even show the slightest interest. I'm not sure she even recognizes them as prey items. Every time I've tried baby rats I find them cuddled up with her on the heat tape, sometimes right in her coils! She gobbles down F/T voraciously though, so I'm not complaining. Definitely odd!
