I want to offer it simply for variety in my snakes' diets. It wouldnt be a staple. Since my little boas are too small to eat stuff like chicks, quails and rabbits, a link here and there i believe would be a good change.
I couldnt imagine how a Reptilink would cause impaction. It's not wet sand or a giant piece of undigestible material. A snake's stomach digests bone, i think it digest a sausage casing. And not all lizards tear their prey unless it is too big. My Nile monitor used to just swallow mice and small rats lol. Big stuff he would hold them in his mouth and then use his claw to rip them open and then drag them around all proud. That made for a big mess. My Savannahs used to just swallow stuff too. My beardie also would just swallow the links.
