I caught a garter about two months back and could tell it was gravid already but was shocked because they snakes is under 20", ik snakes in cities are smaller but i'm still surprised to see one gravid so small.

Well she's still gravid, has shed twice in 2 months and i'm starting to think she's got slugs and can't pass them. She last shed just over a week ago.

How should I go about trying to get her to pass them and what's the likelihood this isn't a long pregnancy period but a case of retained slugs?
