Can Guinea pigs have sugar free cake?

Guinea pigs should not be given any type of cake, regardless of whether it is sugar-free or not. Cakes and other sugary treats are not part of a healthy diet for guinea pigs and can cause a variety of health problems, such as obesity, dental disease, and diarrhea.

Guinea pigs are herbivores and their diet should consist mainly of hay, fresh vegetables, and a small amount of pellets. They should not be given any sugary or processed foods, as these can be harmful to their health.
