I wanted another "super eater" like my boa when I got my coastal mix and wound up with something closer to our royal. Prior to her rabbit 2 days ago she had refused ALL food since May 28th.
Hunger does prevail eventually but I understand when folks get frustrated by refusals. I've tossed out several F/Td rats and fed my BC when I really didn't want to feed him.
In some cases, not all, a carpet will be more enticed by a fairly large prey item. I remember using fuzzy rats and not seeing interest, but when I tried a small rat she hit it rather quickly, that was when she was smaller. Now I feed large everything.
However, that isn't a magic formula here as I am never sure when or what she'll eat.
Silly snake!
