Your grammar screams of maturity and experience.
Anywho. Since I feel like it I'm going to tell you how it is physically impossible for any snake to eat insects. Snakes do not have the reflex of grab, snap, and swallow. They're mouths are also not designed to grab small amounts of food. When the 'feeding reflex' kicks in they BITE-GRAB-WRAP-SQUEEZE-SWALLOW.
Their instincts virtually forbid them from skipping the wrapping and squeezing.
So basically those Petco employees are pretty uneducated. I'm not too sure so don't quote me on this, but I THINK that the digestive system would have an issue with insects as well?
All those insects will do is attempt to eat the snake. Inhumane is what it is.
