Why Can’t Guinea Pigs Eat Bread?

Bread is essentially to guinea pigs what junk food is to humans; it provides no nutritional value for them. This is why we can’t feed our pigs bread due to the importance of feeding our pigs quality food that contains the nutrition they need.

Additionally, guinea pigs have a hard time digesting any type of processed foods, and that includes bread. This can potentially lead to an impaction if given in large quantities, as well as conditions related to too much sugar, protein, and carbohydrates.

Another reason guinea pigs cannot have bread is that they may choke on pieces of bread. They are used to foods like hay and vegetables, so chewing up something like a piece of bread isn’t their “bread and butter.”

Other Processed Foods and Guinea Pigs

Besides bread, there are numerous other foods that you should know are unsafe for your pigs. This list below will help guide you in learning what foods are safe or unsafe for your pet.

Can guinea pigs eat chocolate?

Your guinea pig cannot eat chocolate for a number of reasons, including the sugar and dairy within.

You have to consider that your guinea pig cannot process the amount of sugar or dairy that we can.

Giving your guinea pig chocolate or anything containing high levels of sugar can cause tummy cramps and changes in their stool, such as diarrhea.
