I've ended up with a bottle before, Ive gotten free samples of both Jurassi-Cal and Jurassi-diet, which boasts being a premium diet with out fillers and some other items that affect calcium absorbtion. I dont recall offhand too much but know the pellets atleast had higher nutrition values then most dry food. A small local pet store was trying out the line and wanted my feedback as I deal with them fairly often. Infact Im almost positive I have the Jurassi-diet on one of my shelves still o.0 dont think they cared for it much.
