How could this be listed as cruelty free when it has snail mucin?

If you're like me, you've likely been wondering about this. Turns out, the slime is gathered in snail farms (where escargot comes from) where the creatures are left alone to wander atop a mesh screen for a period of time. They leave mucin in their wake, which is then collected and added to the products, so it is cruelty free for these products.
