Another issue with items like yogurt drops is the amount of sugar they contain. Too much sugar can cause diabetes in guinea pigs the same way it does in humans.
Think about the size of a yogurt drop in comparison to your
GP's size. It's about the equivalent of you eating an entire cake by yourself.
Stick with occational, natural sweets like fruit. Your
GPs will love them just as much, if not more, ad they get the benefit of the natural vitamins and enzymes.
