"Silica gel is non-toxic, meaning that it is not poisonous if eaten. The package says "DO NOT EAT" because (1) it is not food, and (2) it could be a choking hazard. The whole packet, granules, or beads may become lodged in the throat of a small child or animal."www.ncpoisoncenter.org/body.cfm?id=113
That makes sense. I think you'll be fine.
