yes i think thats what they do, although i'm not expert, i mean i doubt they can digest bones and hair etc...

Snakes digest virtually everything. Bones get dissolved in the digestive system usually within 72 hours. It basically all gets turned into mush, which is absorbed by the snake, much the same as you absorb your food.
The only things snakes can't digest are keratin-based products, like hair, claws and feathers etc. They pass through the digestive system and are ejected as waste material.

Our snakes also have problems digesting mice tails, more often than not I am spot picking them 2/3 days after feeds.
