Yes — but only in moderation and prepared correctly.
Celery is safe for guinea pigs when fed occasionally and in small portions, but it should never replace their staple diet of high-quality guinea pig hay.
At HayDay, we’re experts in small animal nutrition, guided by our in-house nutritionist Briony. In this guide, we’ll explain exactly how to add celery safely into your guinea pig’s feeding routine, covering how much to feed, how often, and what to watch for.

Can You Feed a Guinea Pig Celery?
your guinea pig can safely eat celery, including both the stalks and leaves, but only as an occasional treat, not as a daily part of their diet.
Celery provides useful nutrients like vitamins A, C, and K, but it must be fed in moderation to avoid health issues such as kidney or bladder stones. High calcium and phosphorus, plus reduced water intake, are the main dietary factors that can contribute to these problems.
Preparation is key: always wash celery thoroughly, remove any hard strings, and serve it in small, manageable pieces to reduce the risk of choking and digestive upset.
Can guinea pigs eat celery sticks and leaves?
Yes, guinea pigs can eat both celery sticks and celery leaves.
Your guinea pig should be limited to around 4 grams of celery per day – that's the equivalent of one short strip. Celery should be given sparingly and never become a staple in their regular diet.
Every part of the celery plant – stalks, leaves, and even the base – is safe for your guinea pig to eat in small amounts.
Treats are fine, but only when they support your pet's wellbeing. Understanding the nutritional benefits of celery helps you decide how to include it as an occasional snack rather than a core food.
Is celery good for guinea pigs?
Celery is more than just a crunchy treat. It contains valuable nutrients that support your guinea pig's health:
-
Vitamin A supports organ function, the immune system, and good vision.
-
Vitamin C is important because guinea pigs cannot make their own. Celery contributes some of this essential nutrient, helping to prevent scurvy and support the immune system.
-
Vitamin K supports proper blood clotting and bone formation.
While celery isn't the highest source of vitamin C compared with other vegetables, it still adds useful nutrition when fed occasionally as part of a varied diet.
How much celery can guinea pigs have?
Celery is a wholesome treat, but it must not overwhelm your guinea pig's diet. The right amount and frequency are key.
Frequency
Celery should be an occasional treat, not a regular part of their daily diet. Feed celery no more than twice a week. This helps maintain a balanced diet with a variety of vegetables. Think of celery like a small slice of cake for you – enjoyable in small amounts, but not healthy as a daily food.
Portion size
Portion size is just as important as frequency. A safe portion is around a 2-inch section of celery per guinea pig. Include some leaves with the celery section – they are beneficial for their diet. A full celery stalk is too much and should not be fed.
Can guinea pigs eat green celery?
Yes, green celery is the classic, most common variety and is safe for guinea pigs in moderation. It should be washed thoroughly, cut into small pieces, and fed only occasionally as part of a balanced diet.
Can guinea pigs eat golden celery?
Yes, golden celery is a paler, slightly sweeter variety that is also safe for guinea pigs in small amounts. Like green celery, it should be washed, trimmed, and cut into manageable pieces before feeding.
Can guinea pigs eat red celery?
Yes, red celery is less common but still safe for guinea pigs if washed and cut properly. It should be treated the same as other celery varieties – fed in small amounts and only occasionally.
Can guinea pigs eat celery leaves?
Yes, guinea pigs can eat celery leaves, and they are often more nutritious than the stalks and lower in oxalates. Leaves can be offered alongside a small section of stalk, but always in moderation.
Can guinea pigs eat baby celery?
Yes, baby celery is usually sold trimmed and ready-to-eat, but it still needs washing and cutting into small pieces before feeding. It is safe for guinea pigs in small amounts as an occasional treat.
Can guinea pigs eat celery root (celeriac)?
Guinea pigs can eat celery root, also known as celeriac, in tiny amounts, but it is higher in starch and should be very limited. It is not a regular part of their diet and should only be offered occasionally in very small quantities.
All celery variants should be washed thoroughly, cut into small bite-sized pieces, and fed only occasionally. Avoid feeding cooked, seasoned, or pickled celery, as these are not suitable for guinea pigs.
Potential hazards when guinea pigs eat celery
Celery can cause problems if fed too often or in large amounts. Celery is a high-oxalate food, which can contribute to kidney or bladder stones if your guinea pig consumes large amounts or frequent servings, due to its calcium content. This doesn't mean celery must be eliminated entirely, but it should be fed sparingly.
The stringy fibres in celery can be a choking hazard. Always cut celery into small manageable pieces and remove tough strings before feeding. Guinea pigs with a history of bladder stones, kidney issues, or urinary problems should avoid celery entirely or have it only under veterinary guidance.

How do I prepare celery for my guinea pig?
Preparation is crucial when feeding celery. Always feed raw celery – it retains more nutrients than cooked celery and is easier for guinea pigs to digest. Wash the celery under clean running water to remove pesticides and contaminants before offering it to your pet.
Peel or trim any tough outer strings if they look particularly fibrous. Cut the celery into small pieces, roughly the size of your pinky nail, to reduce choking risk. Remove any wilted or discoloured parts and discard any leftover celery after about an hour to avoid bacterial growth. Never feed seasoned, salted, buttered, or cooked celery.
What vegetables can I give my guinea pig instead of celery?
Celery is a good snack, but it's important to diversify treats with a variety of vegetables. Nutritious leafy greens include kale in moderation, spring greens, romaine lettuce, and dark-leaf lettuces.
Vegetables like colourful bell peppers and broccoli leaves are excellent choices, and you can offer small amounts of cabbage on occasion. Flavourful herbs such as parsley, mint, coriander, basil, and dill are also great additions.
As occasional treats in small amounts, guinea pigs can enjoy apples without seeds, bananas, berries such as strawberries and raspberries, and small amounts of melon. For more on apples, check our guide on can guinea pigs eat apples.
Introducing a mix of these vegetables is very healthy. Remember that cooked foods are not suitable for regular consumption by your guinea pig. You can also grow fresh veggies and herbs in your garden, giving your guinea pig direct access to crisp, safe snacks.
How do I introduce new foods to my guinea pig?
When introducing new foods, including celery, it's important to monitor your guinea pig closely. Watch for changes in food and water consumption, the appearance of their droppings, and any unusual changes in urine or stools that may indicate an adverse reaction.
Be especially attentive during the first few introductions of new vegetables. If you're concerned about your guinea pig's wellbeing after trying new foods, seek advice from a vet. For more on monitoring your pet, you can read our rabbit poop check guide for useful tips on spotting health issues.
What should a balanced guinea pig diet include?
A healthy guinea pig is not about celery alone; it's about maintaining a balanced diet. Key components of a guinea pig's diet include fresh guinea pig hay, which should form about 80–85% of their diet and be offered as unlimited, free-choice hay. This is essential for good digestion and dental health. Browse our range of guinea pig hay here.
Daily servings of pellets – around an egg cup full per day – are also important. A handful of freshly washed leafy greens, rich in vitamin C, completes the core diet.
Following these guidelines helps ensure your guinea pig has a well-rounded diet that keeps them healthy and happy for life.
Summary
Celery can be included safely in your guinea pig's diet, but with clear limits. Yes, guinea pigs can eat celery, but it should be given in moderate amounts – around a 2-inch section, twice a week.
Proper preparation is key: wash the celery, remove strings, and cut into small pieces. Variety is fundamental: celery should be one of many safe vegetables in a balanced diet. Common variants like green, golden, red, baby celery, and celery leaves are all safe in small amounts when prepared correctly.
