Can Guinea Pigs Eat Celery? Yes, in Short, Thin Pieces
Yes, guinea pigs can eat celery, stalks and leaves both, as part of a varied vegetable mix. It is crunchy, low in sugar and watery, and it gives a guinea pig something to chew between mouthfuls of hay. Two things matter: cut the stalks into short pieces so the long strings cannot tangle, and do not rely on celery for vitamin C, which guinea pigs cannot make themselves. Bell pepper or other vitamin C-rich vegetables should share the bowl.

Why celery suits guinea pigs
VCA Animal Hospitals recommends offering guinea pigs a variety of fresh, well-washed leafy greens and colorful vegetables every day, alongside hay and pellets. Celery is a mild, low-sugar vegetable that fits that mix, and its crunch encourages chewing.
Hay stays at the center. VCA calls hay the most important part of a guinea pig's diet and recommends unlimited timothy or other low-calcium hay throughout the day, because it feeds healthy gut bacteria and helps wear down constantly growing teeth. Merck agrees that hay should be available at all times.
Strings, water and vitamin C
Celery's long fibrous strings are the practical hazard. A guinea pig chewing a long stalk can end up with strings caught in its teeth or bunched in its mouth. Slicing the stalk crosswise into short pieces, about the width of a fingernail, shortens every string at once.
Celery is also very watery and contains little vitamin C. Guinea pigs cannot make their own vitamin C and need it from their diet daily, as both VCA and Merck explain, so celery should never be the main vegetable. Merck warns against iceberg lettuce for being mostly water; celery is more useful, but the same portion logic applies.
How to prepare celery
Wash the celery well under running water and slice the stalks crosswise into short, thin pieces. The leafy tops are tender and can be chopped roughly. Serve it raw, fresh and crisp; throw out anything limp, slimy or moldy.
Offer celery in the vegetable dish with other produce rather than on its own. Remove uneaten pieces within a few hours so they do not spoil in the cage, and never offer celery from soups, dips or stuffing, which brings salt, onion and fat.
Guinea pigs need floor space as much as fresh food; a small animal playpen or a large indoor cage gives them room to explore between meals.
How much celery can a guinea pig have?
A few short pieces of stalk plus a little leaf, a small spoonful in total, is a sensible portion for an adult guinea pig as part of the day's vegetables. Celery can appear a few times a week in rotation rather than every day.
Introduce it gradually if your guinea pig has not had it before. VCA notes that guinea pigs do not adapt easily to changes and that sudden changes can result in a refusal to eat, so start with a single piece.
Pair celery with vitamin C-rich vegetables
VCA lists bell pepper, tomato, turnip, collard greens and asparagus as vegetables high in vitamin C, and romaine and red leaf lettuce, broccoli, cauliflower, carrot tops, beet greens, cilantro and squash among other good choices. A bowl that combines celery with one of the vitamin C stars covers both crunch and nutrition.
Fortified pellets help too. VCA advises using or replacing guinea pig pellets within 90 days of manufacture because their vitamin C breaks down over time, and Merck warns not to substitute rabbit pellets, which do not contain enough vitamin C for guinea pigs.
Signs of trouble and when to call a vet
Soft droppings after a large helping of watery vegetables usually settle once the guinea pig is back on its normal mix. A guinea pig that drools, paws at its mouth or struggles to chew may have a string or a dental problem and should be checked.
VCA lists a rough coat, loss of appetite, diarrhea, reluctance to move or signs of pain, swollen feet or joints, and bleeding or ulcers on the gums or skin as signs of vitamin C deficiency, and advises seeing a veterinarian as soon as possible. A guinea pig that stops eating also needs a vet promptly.
Other vegetables to rotate in
Bell pepper strips, romaine lettuce, cilantro and carrot tops are reliable favorites. Merck advises that high-calcium greens such as parsley, kale and spinach should not be given often, because excess calcium may contribute to bladder stones.
VCA says not to feed oats, seeds, nuts or dry cereals, which are too high in carbohydrates and fat, and to avoid iceberg or head lettuce. Ask your vet about the best vitamin C sources for your own guinea pig.

Common questions
Can guinea pigs eat celery leaves?
Yes. The leafy tops are tender and safe, and many guinea pigs prefer them to the stalk. Wash them well and add a small amount to the day's mixed vegetables.
Can guinea pigs eat celery every day?
A few pieces now and then is better than daily. Rotate celery with other vegetables, especially vitamin C-rich ones such as bell pepper, so the diet stays varied and complete.
Do I need to remove celery strings for a guinea pig?
Slicing the stalk crosswise into short, thin pieces shortens the strings enough. Peeling the outer strings off with a vegetable peeler is optional extra caution.
Does celery give guinea pigs vitamin C?
Only a little. VCA names bell pepper, tomato, turnip, collard greens and asparagus as better vegetable sources, and fortified guinea pig pellets supply vitamin C as well.
Can baby guinea pigs eat celery?
Young guinea pigs can try a tiny piece of celery leaf once they are eating hay and pellets well. Introduce it slowly and watch their droppings over the next day.
