I also found a produce place that makes up there own bags of Guinea Pig food of pellets. They assure me there is no salt added. Also, I can get bales of packed alfalfa hay that gardening stores sell as mulch. The local horse places have been terrible to find it: all the horse food reads like dog and cat food now. You know, with vitamins and additives to help it win the grand national with bones of steel or the like.
