Guinea pigs love tomatoes, but only the ripened fruit is safe for them. Unripened tomatoes contain tomatine – a glycoalkaloid poison which may lead to diarrhea in guinea pigs – while green tomato leaves and stems should also be avoided as these could contain phytotoxins that are toxic for them.
Tomatoes may provide important vitamins and minerals such as Vitamin C and potassium for guinea pigs, but kale, dandelion greens and sweet red bell peppers offer much more nutrition for these tiny rodents. Tomatoes also contain high acid levels which may lead to mouth sores when fed to guinea pigs.

Cherry Tomatoes
Guinea pigs love munching on tomatoes! Cherry tomatoes, plum tomatoes and beefsteak tomatoes (cut into smaller pieces) all provide ample vitamin C as well as ascorbic acid to prevent scurvy and are rich in dietary fiber essential for digestive health.
However, it’s essential to remember that any type of tomato should only be fed in moderation as its high sugar content can lead to obesity and other health problems in the long term. Furthermore, any non-fruit part of a tomato such as its stems or leaves must not be fed directly as these could contain harmful compounds and be detrimental for their wellbeing.
Note that while tomatoes do provide an adequate source of vitamin C, other sources like kale, dandelion greens and sweet red bell peppers contain 10 times more. Although these other fruits and veggies may be less convenient, they will ultimately provide your guinea pig with greater health benefits.
Grape Tomatoes
Grape tomatoes provide your guinea pig with an ideal treat, offering sweetness without as much sugar content that could potentially alter their gut flora. But be careful not to give too often; their high level of oxalic acid could potentially cause cheilitis (scabs in the mouth).
Tomatoes provide essential vitamins and minerals, particularly vitamin C, that will support your guinea pig’s wellbeing. Plus, their high water content and fiber content help promote digestive health. Beware unripe green tomatoes as these may contain solanine (an alkaloid poison). In addition, some guinea pigs may experience allergic reactions to tomatoes which result in swollen lips/tongue/labored breathing – in this instance stop feeding them tomatoes immediately and consult your vet immediately!
Plum Tomatoes
Tomatoes are an excellent source of vitamin C, an essential nutrient for guinea pigs that can prevent scurvy. Not only are tomatoes low-cal and rich in fiber content; they’re also extremely low-calorie!
However, they must only be fed when completely ripe and should never contain green parts such as leaves or stems as these contain solanine – an alkaloid poison present in nightshade plants that may lead to solanine poisoning in guinea pigs who consume unripe tomatoes and other nightshade plants.
Tomatoes can be highly acidic, leading to sores in their mouth if given too quickly or in large doses. Due to their high water content and acidic nature, tomatoes should only be given in small doses gradually over time – starting by offering one or two tomato pieces every few days and gradually increasing frequency and size over a few months.
Beefsteak Tomatoes
Although guineas pigs do consume tomatoes, care must be taken not to give them any non-fruit parts such as stalks or leaves that could prove poisonous to their health – including stems, leaves and stalks which contain tomatine which has been identified as being toxic in high quantities.
Once it comes to tomato fruit itself, guineas can consume small quantities a few times each week in small amounts – cherry tomatoes or smaller varieties should be the ideal snack option; larger tomatoes contain too much tomatine for your pet to consume safely and healthily.
Tomatoes are an excellent source of vitamin C, an essential nutrient for guinea pigs as they cannot produce their own. Instead, they rely on other sources, like diets rich in vegetables to get this essential nutrient that aids with iron absorption, immune support and wound healing. Vitamin C helps guineas absorb iron while supporting overall body regulation.
