How often to feed tomatoes and how much?

Guinea Pigs cannot eat tomatoes every day, nor should we introduce them into their diet for the first time abruptly. These small rodents are very sensitive to changes and their gums tend to get irritated easily, so we should start serving them small pieces of tomatoes along with their usual food until you have got used to them.

Otherwise, we could cause a disturbance of your digestive system that is highly susceptible to changes, and begin to observe symptoms such as acute diarrhea.

You will need to serve a small portion equivalent to the size of a cherry tomato or a slice of a large tomato. In addition, it will always be preferable to give it to you in pieces so that you can chew them more easily and have no problem swallowing.

PLEASE NOTE: You must remove the vine stem and leaves from the tomato before feeding to your pet guinea pig. These are extremely poisonous to guinea pigs.

Uneaten tomatoes should be removed within an hour of feeding them to your guinea pig. Tomatoes and other soft fruits attract fruit flies and other germ-spreading insects and you want to avoid your piggies eating any tomato or other foods that have been contaminated by these creatures.
