I have only 13 ball pythons but two of them seem to have a color preference tending to prefer white rats over dark rats.
The axanthic will not take a dark colored rat. Period. If offered a hooded rat, she will refuse. Turn the rat around (to have the white body facing her) and she will attack and consume. I also have a female pastel who does the same thing.
I have performed this little experiment over and over and over and the axanthic is absolutely consistent with refusing a dark headed rat. Is this conclusive? Nope- I'm not in a lab controlling every variable but the one being tested.
Is this suggestive? To me it sure is!![]()
