How do you make a cake for your guinea pig?

You should not feed your guinea pig cake, as it is not a suitable food for them. Guinea pigs have sensitive digestive systems and should only eat a diet of hay, fresh vegetables, and a small amount of pellets. Cake contains processed sugar, unhealthy fats, and other ingredients that can be harmful to guinea pigs. If you want to treat your guinea pig, you can give them a small piece of fresh fruit or vegetable.
