I believe it was Petsmart that pushed these when they first started selling snakes (corns) years ago. They weren't big on selling snakes that ate rodents so they required them to be fed the sausages and told the customers that's what they ate. Needless to say, I had plenty of customers come into the store I was managing at the time that couldn't get there baby corn snake they bought at Petsmart to eat. How shocking that it usually only took one attempt with a pink to get them going.
