harmful to snake diet?

[PatrickBateman]

Just a general question for my own curiosity...

If a snake is eating a feeder mouse, it is then in turn also eating what the feeder mouse ate. Are there any potentially harmful things to a snake that are not harmful to a mouse, but the snake eats anyway because it is already inside the mouses stomach?

If the mouse has a "gut load" of one of the following: corn, bread, nuts, vegetables, rice, can there be a danger to the snake? Does the mouse stomach do something to neutralize any harmful effects, or is it perfectly fine for a snake to inadvertently eat small quantities of non-meat products?

Thank you.

It shouldn't be a problem. Most feeder mice are fed lab blocks, which are mostly grain. The better brands have no animal products whatsoever.

You do have to be careful with pet store mice.
Some of them use flea powder on their mice.
