Well, they're from different parts of the world, but I think that they are both from dry grasslands type areas. I don't think that would make a difference though. My point is that Gerbils are not any more 'natural' of a food item then any other rodent. A wild ball python would never run into a wild Gerbil. I don't know what the attraction is, I guess it would probably be smell though. Maybe Gerbils just smell more like what ball pythons think 'food' should smell like then either rats or mice. There is no denying that some balls are very particular about what they will eat, and many seem to be attracted to Gerbils over either rats or mice. I have a friend that has a WC ball python that she's had for over 20 years. The thing eats 4 or 5 Gerbils a year and won't touch anything else. I guess it doesn't make sense to me WHY they prefer Gerbils, but if thats all they'll eat, thats what they should be fed. I think these snakes are just really good at training US.

>>Mark, although I was the first one to post that, I always thought Gerbils were from a different climate than Balls. They do seem to prefer the gerbils over either mice or rats though. With my snakes it's more important to get an appropriate size food item than it is a particular species. They won't take mice, but a hamster, gerbil or rat doesn't make a difference.
