Oh, good question. I'd love to know how they respond. I've only used Reptilinks in a limited way, so have placed only a few orders with them. I used the quail links as a primary food for a young Dumeril's who was a real problem feeder for two freaking years - I wanted the caloric density of the links - and as an occasional treat for any of my other snakes who would take them (most of my snakes like them).
But I've honestly stepped back from using them. I think they are a fine food source, but many of my snakes strike the links so hard that they sort of blow them apart. And after that they either eat only part of it or seem to lose interest in the mess. I don't like wasting food or feeling like the feeder animals died for no reason, so I doubt I will re-order since the Dumeril's is now happily eating chicks (thank GOD).
