Guinea Pig Treats
Before buying treats that are labeled suitable for guinea pigs, do check the ingredients. It’s surprising how many contain sugar and other unsuitable ingredients
Some of these treats may also contain mealworms which are not suitable either as they are a form of meat.
Certain fresh fruits can be fed to your cavy but should only be given as an occasional treat. When you do offer this to your guinea pig, always make sure that you remove any stones.
