Humans can digest bone too, but we are still able to get parasites from the food that we eat.

Feeding frozen thawed in my oppion is much better. If a rodent is frozen for at least 30 days it eliminates any parasites that can be passed on to your snake.

Tapeworms parasitize the digestive system. Roundworms and related parasites inhabit the digestive tract, but their juvenile stages can cause disease to other organs (especially the lungs).

Snakes can be hosts to large number of parasites, representing a bewildering variety of organisms that can cause many problems to the reproductive and vascular (blood and bloodstream) systems of snakes.

It is possible for a captive snake to become parasitized by eating prey species that harbor the larval stage of a given parasite. Hence if you freeze it, you will eliminate the risk of your snake getting an internal parasite

Dont diss everyone at petco, becuase some of them no what they are talking about, They gave the rite information and passed it on. I dont have a petco here, but it seems like they take alot of heat for things, but in this particular case they gave nothing but 100% factual information.
