Episode 9: Guinea Pigs and Hay

Guinea pigs should have a diet that is at least 80% hay, which helps to reduce the risk of dental disease and gastrointestinal issues. It can be challenging getting them to eat a healthy diet sometimes, just like us.

Nicole and Jez talk about why hay is so unique as a food, as well as why it can help with normal dental wear and digestion.
