I have a pair of het for albino ball pythons. I have never fed them anything but rats but I can't fail to notice that they are much less aggressive feeders than my Mojave or Spider. I have speculated as to why this is. I have read that Mojaves and Spiders generally have a strong feeding response. I have also read that Albinos (not hets) are often finicky eaters. But the hets also become inactive and stay in their hides on the same days as well as fail to eat on the same days and I have wondered if they behave in similar ways because they are also siblings.
