I find that dairy products are one of those foods that people either love and are restricted to eat because of some kind of health restriction.
Dairy can be anything that can be made from milk and Foods such as butter and cream are loved throughout the world for their versatility and taste.
So if we can eat dairy products,
Unfortunately, guinea pigs belong in the group that can’t eat dairy because if their health. This because they are lactose intolerant. This is basically the inability to digest lactose, a sugar found in milk and to a lesser extent milk-derived dairy products.
This means that they can’t eat any kind of milk products. If they were to eat them at all, they would become sick or get diarrhoea.
So if you have any dairy products do not feed them to your guinea pigs at all. Instead give them water, hay and veggies which are much better for them.
