I can see that concern but remember snakes eat rats and rats have some really sharp claws. Then snakes in the wild eat a wide range of things that you would think could hurt their insides but doesn't. Have you ever heard of that being an issue? I haven't. Snakes are amazing.
Yes, I've heard of that- snakes have been injured by claws etc when regurgitating freshly swallowed prey. Snakes are amazing but not invulnerable...
