i have my 3 all on f/t now (took some doing to get my male to take f/t).

my largest female has never refused anything i have offered her be it live f/t mouse or small rat or even color ... its all food to her and she's gonna eat it.

my male on the other hand will only take white mice when i was still feeding him live it had to be white or he would hide from it. knowing that i have not even tried to feed him any other color f/t and it still has to be mice, he wont take a rat no matter what i have tried.

my newest little female i dont think i would have a problem getting her to take a rat once she gets a little bigger, she's not picky either (so far).

they all have their own personality or quirks just a matter of knowing your animal and learning to live with their quirks
