Excellent food recommended by the experts on Guinea pigs

Recommended so I tried it. My Guineas hate pellet food, but they love this stuff. The pellets look better than the usual kind offered at a lower price.

This is the only food they like. We’ve tried switching them back over to Oxbow when this was out of stock and they refused to eat. They wait with eager anticipation

Rare to find guinea pig pellets with no alfalfa!

Due to bladder stones, my piggy needed to limit her calcium intake. It was hard to find pellets with no alfalfa, and my little miss picky pig even eats them!
