[Snaky]

This is not a checkered problem, but it manifests itself more with a checkered garter because, like you said, they eat about anything and a lot if given the opportunity. But any snake that eats well is a good candidate to get fat.

Most of the time people just give to much food to their snakes, most pythons and boa's have way to much fat. Luckily for us, garters are quite active snakes, so they exercice a bit and most of them eat a rather amount of fish.
