I dont feed them to my leos or AFTs. They are very fattening and hard to digest, they are okay as a treat once in awhile if you really want to feed them but I personally dont feed them.
I feed them to my fatties no problem during breeding season. My females get a live pinkie after each clutch, I find it helps them maintain their weight during the stress of laying.
my AFT love's them, for a while he went on really long, not eating binge, and i was feeding 1 every two weeks to help get him back up to weight, he eats them like a fat kid eats a twinky.
