Also keep in mind, snakes in the wild don't often have people tracking their every move, noticing when they get infections or die. I've heard of them having problems in the wild with strange objects or unusual prey items they shouldn't be eating, not so much rodent claws because of the way the limbs bend when being swallowed but what Bogertophis is saying makes plenty of sense. I've certainly heard my fair share of stories in captivity of impaction and regurgitating problems though I've never personally dealt with it, knock on wood.
