As you can see tomatoes contain a hint of sugar, phosphorus, and fat and they contain quite a bit of phosphorus and acidic content.

They also have a very good amount of vitamin c in them which is great for piggies.

This means that guinea pigs can eat tomatoes.

Two to four times a week should suffice for them as tomatoes contain just a little too much acid to be eaten every day.

They can eat the skin and the seeds as well which are fine for them to consume.

Make sure that the tomato is washed thoroughly and cut up for them to eat. A few slices at a time is more than sufficient for them.

This is good news for guinea pigs and provides a welcome addition to their diet of regular hay, guinea pig mix and veggies. The vitamin c content is very good for them.

A few small pieces at a time, but not too much due to their high acidity.
