If you see such symptoms, you need to stop the feeding process and offer your guinea pigs plenty of water.

Besides, guinea pigs should not eat any type of food that contains seeds because of a possible choking hazard.

Stomach Problems

If your guinea pig consumes too many apples, it can get stomach pains. This’s because of sugar and acidity in the green apples. For this reason, you need to limit the number of apples that you give your guinea pigs.
