For 30 yers I have been raising all sorts of reptiles. When I started raining Asian and Central American pit vipers I used to use greenhouse frogs I collected, treated for parasites, and housed and fed until it was snake feeding time. Reptilink frog sausages have cut out all the time spent capturing, worming, and feeding up those little frogs. Most of the tiny hatchlings will take the reptilink micro frog sausages with a little tease feeding much easier than pinky parts in my experience. I also feed them to baby turtles to add more diversity in their diets. Great product!!!!
