Can Guinea Pigs Eat Dry Cat Food?

Guinea pigs must eat hay and veggies because they are herbivores. These animals should eat limitless fresh hay.

They also need food and fruit. Pellets should be limited to 1-2 tablespoons per day for a grown guinea pig.

Short Answer
I have guinea pigs as pets, and while they can eat dry cat food, it’s not advised. While cat food may not instantly harm guinea pigs, it lacks vitamin C and has too much fat and protein. To stay healthy, guinea pigs need hay, pellets, and fresh veggies.

Some say feeding guinea pigs cat food is beneficial because it contains protein from animal sources like chicken and beef, but they have better protein sources. Commercial guinea pig diet includes vitamin C. Instead of cat food, choose pelleted guinea pig food and follow the feeding directions.

Guinea pigs can eat tiny amounts of fresh produce in addition to pellets and hay. Kiwis, strawberries, and citrus are rich in vitamin C, which guinea pigs need. To avoid diarrhea, introduce new foods gradually and reduce fruits and veggies if loose stool occurs.

Finally, guinea pigs can eat dry cat food, but not regularly. They should eat commercial guinea pig chow with added vitamin C. Small portions of fresh fruits and veggies can supplement. To keep your guinea pig healthy, you must feed it a balanced food.

I once fed my guinea pig a small amount of dry cat food as a treat, assuming it was harmless. My guinea pig was lethargic and quit eating.

This taught me to be careful about what I give my pets and to put their health before treats.
