How Much Tomato Can A Guinea Pig Eat?

That’s a great question and we’re glad you asked!

Here’s how much tomato a to feed your guinea pig:

Age Amount
Baby guinea pig None
Adult guinea pig 2 to 3 cherry tomatoes or equivalent

If you’re in the habit of adding cherry tomatoes to your own salad, you can feel free to give some tomato to your guinea pig at the same time. If you slice up larger tomatoes, you can offer as much as two tablespoons at a time.

Just like any other new food, tomato needs to be introduced gradually. Start by giving your cavy about ½ a cherry tomato or a teaspoon of sliced tomato.

Watch your pet carefully for the next 12 hours, looking for signs of abdominal discomfort or diarrhea. If everything goes well, you can gradually increase the amount of tomato you offer over the next several days until your cavy is eating a full serving of tomato.

How Often Can A Guinea Pig Eat Tomatoes?

Tomatoes do contain sugar but not nearly as much as other fruits have. It’s OK to give a cavy tomato up to four times weekly, but not on the same days as other acidic foods since too much acid can lead to mouth sores.

Cut back tomatoes, apples, grapes, and other acidic treats if you notice a problem; things like cucumber, celery, and watermelon might be better for the time being.

The Correct Diet Is Important

Guinea pigs are native to South America, where their natural diet consists of low-growing plants and grasses. It’s vital to provide your pet with a diet that’s as close to all-natural as possible!

Each day, ensure that your cavy has access to:

  • Guinea pig pellets with vitamin C added (See the label for the correct serving size)
  • Unlimited fresh hay such as Timothy for nibbling, nesting, and tunneling; the constant chewing will help keep your guinea pig’s teeth from becoming overgrown and the fibers will keep their digestive system running smoothly
  • Fresh, clean water; rinse and refill your guinea pig’s drinking bottle at least once each day
  • About one cup of fresh vegetables daily, preferably divided into two portions and offered at different times

    Interesting article. I was particularly interested to read that guinea pigs cannot eat tomato stems and leaves. It is great that you have included this in the article. This is something that people should take great care over, especially if they have tomato plants growing near where their guinea pigs live.
