Can Cats Eat Beets? Roots, Greens, and Oxalates
By Dr. Zubair Khalid, DVM, MS, PhD ·
Can cats eat beets? Yes, in small amounts, if the beet is cooked and plain. Cooked beetroot is not toxic to cats, and a tiny piece now and then is generally fine. Raw beet greens are a different story because the mature leaves contain oxalic acid, which matters for cats with urinary or kidney problems.

Quick Answer
- Cooked, plain beetroot is non-toxic to cats and can be offered as a rare, tiny treat, not a meal [1].
- Raw or lightly cooked mature beet leaves and beet tops contain oxalic acid and should be avoided, especially for cats with a history of calcium oxalate bladder stones [1].
- Never feed beets canned in brine, pickled, or seasoned with salt, garlic, onion, or xylitol. Those additives are the real danger, not the beet itself.
- A safe serving is roughly a pea-sized piece of cooked beet, no more than once or twice a week, and it should stay under 10 percent of your cat's daily calories.
- If your cat eats a large amount of raw beet greens or any seasoned beet product, call your veterinarian or a pet poison hotline right away.
Can Cats Eat Beets? The Short Verdict
Beets are listed as non-toxic to cats by the ASPCA Animal Poison Control Center, which classifies Beta vulgaris (beet root, red beet, sugar beet, and Swiss chard) as non-toxic to cats, dogs, and horses [1]. That means the plant itself will not poison your cat in the way that, say, a lily or sago palm would. The same record notes that large mature leaves contain oxalic acid, which is the part owners need to think about [1].
So the honest answer is: cooked beetroot is safe as a tiny occasional treat, and raw beet greens are best avoided. This is not a food your cat needs. Cats are obligate carnivores, meaning they evolved to get their nutrition from animal tissue, and beets do not fill any nutritional gap in a cat's diet. Treats like this are about variety and enrichment, not health benefits.

Nutrition: What Is Actually in a Beet?
Beetroot is mostly water and carbohydrate, with some fiber, folate, manganese, and potassium. It also contains pigments called betalains, which give beets their deep red color. None of these nutrients are needed by a cat on a complete and balanced diet, and the amounts in a pea-sized piece are trivial.
The one nutrient worth mentioning is potassium. In cats, increasing dietary potassium has been shown to increase water intake and urine production and to lower urine specific gravity in a dose-response manner [2]. Higher urine volume is generally considered protective against stone formation because it dilutes minerals in the bladder. That said, the potassium in a small piece of beet is nowhere near the levels used in that research, so you should not think of beets as a treatment for urinary health. If your cat needs more potassium or more water intake, your veterinarian will address that with diet, not table food.
Beet greens do carry real nutrients, including vitamin A, vitamin C, and folate. The problem is the oxalate load in mature leaves, which is why the greens are the part to skip [1].
Can Cats Eat Beets Raw?
Raw beetroot is firm and dense, and cats do not chew it well. The bigger issue is choking and digestive upset. A chunk of raw beet can lodge in the mouth or throat, and the fiber load can cause vomiting or diarrhea in a cat whose gut is not used to it.
Raw beet greens are the more serious concern. The ASPCA notes that large mature leaves contain oxalic acid [1]. Oxalic acid binds calcium in the gut and is excreted in urine, where it can contribute to calcium oxalate crystals and stones. In cats, calcium oxalate is the dominant stone type in the upper urinary tract, making up about 98 percent of kidney stones in one study of cats with upper urinary tract urolithiasis [3]. That does not mean one leaf causes a stone. It means that if your cat already forms oxalate stones, adding an oxalate-rich food works against you.
There is also a gut angle. Cats with kidney stones have been found to have a less diverse intestinal microbiota, and researchers have suggested that the loss of bacteria capable of degrading oxalate could play a role in stone formation [3]. Feeding a high-oxalate food to a cat with that kind of gut profile is a reasonable thing to avoid.

Can Cats Eat Beet Leaves, Beet Tops, or Beet Greens?
This is the question with the clearest answer: no, not raw, and not in any real quantity. Beet leaves, beet tops, and beet greens all refer to the same leafy portion of the plant, and the mature leaves contain oxalic acid [1]. Young, tender leaves from a home garden have less oxalate than large mature ones, but there is no reliable way for you to measure the oxalate content of a leaf in your kitchen.
Cooking does not remove oxalate. Boiling can leach some oxalate into the cooking water, but it does not eliminate it, and you would still be feeding a food with no nutritional need for a cat. The risk-to-benefit math does not work.
If your cat has ever had calcium oxalate stones, chronic kidney disease, or a urinary blockage, treat beet greens as off the menu. Cats with these conditions already have abnormal urine chemistry. One study comparing urine metabolomic profiles in cats with calcium oxalate stones, cats with renal disease, and healthy cats found distinct metabolic differences between the groups, which supports the idea that these cats have different handling of minerals and metabolites in urine [4].
Risks Beyond Oxalate
The beet itself is the least of your worries in most kitchens. The way beets are prepared is where cats get into trouble.
- Salt. Canned beets and pickled beets are high in sodium. A cat's sodium needs are low, and a salty treat can cause thirst, vomiting, or worse in a cat with heart or kidney disease.
- Garlic and onion. Pickled beet recipes and some roasted beet dishes include onion or garlic. Both are toxic to cats and can damage red blood cells.
- Xylitol. Some reduced-sugar beet products and beet-based sweeteners contain xylitol, which is dangerous for pets.
- Vinegar and brine. Pickled beets are acidic and salty and can irritate the stomach.
- Choking. Hard raw beet chunks are a choking hazard, especially for cats with dental disease or missing teeth.
- GI upset. Any new food can cause vomiting or diarrhea. Beets are high in fermentable fiber, which some cats tolerate poorly.
If you want to give your cat a protein-based treat instead, Can Cats Eat Eggs is a better fit for a carnivore. For dairy questions, see Can Cats Eat Cheese, which explains why most cats handle cheese poorly.
How to Offer Beets Safely
If you want to let your cat try beetroot, keep it simple and small.
| Form | Safe? | Notes |
|---|---|---|
| Plain cooked beetroot, steamed or boiled, no salt | Yes, tiny amount | Pea-sized piece, once or twice a week at most |
| Raw beetroot chunks | No | Choking and GI upset risk, hard to chew |
| Raw beet leaves, tops, or greens | No | Mature leaves contain oxalic acid [1] |
| Cooked beet greens | Not recommended | Cooking does not remove oxalate, no nutritional need |
| Canned beets | No | High sodium, often with added sugar |
| Pickled beets | No | Salt, vinegar, and often onion or garlic |
| Beet juice | No | Concentrated sugar, no fiber, no benefit |
| Beet powder or beet supplements | No | Unregulated, concentrated oxalate possible |
When you offer cooked beet, cut it into a piece no larger than a pea. Mash it slightly with a fork so your cat does not have to chew a firm cube. Offer it plain, at room temperature, and separate from your cat's regular meal so you can see whether it causes any stomach upset. Watch for vomiting, diarrhea, or a change in appetite over the next 24 hours. If any of those happen, skip beets in the future.
Treats of any kind should stay under about 10 percent of your cat's daily calorie intake. For most adult cats, that is a very small number of calories, which is why a pea-sized piece is the right scale. Your veterinarian can tell you the exact calorie target for your cat based on weight, body condition, and any health conditions.
One more note on water and urine. Wet food increases water intake and urine volume and lowers urine density compared with dry kibble, and diets with a higher protein-to-starch ratio have been shown to reduce urine oxalate concentration and lower the relative supersaturation of urine for calcium oxalate [5]. If stone prevention is your goal, the moisture and macronutrient content of your cat's main diet matters far more than any treat.
What If Your Cat Ate Too Much or the Wrong Kind?
If your cat ate a small piece of plain cooked beet, there is usually nothing to do but watch. Mild stomach upset is possible, and it typically resolves on its own within a day.
Call your veterinarian or a pet poison hotline right away if your cat ate:
- A large amount of raw beet greens or beet tops
- Any pickled, canned, or seasoned beet product
- Anything containing onion, garlic, or xylitol
- A whole raw beet or a large chunk that could be stuck
Signs that need same-day veterinary care include repeated vomiting, diarrhea, drooling, pawing at the mouth, gagging, lethargy, or refusing food. Signs that need emergency care now include trouble breathing, collapse, a distended abdomen, or an inability to pass urine. A cat that cannot urinate is a medical emergency and can die within a day or two without treatment.
Do not try to make your cat vomit at home. That decision belongs to a veterinarian who knows your cat's history.
Limitations and When to Contact a Veterinarian
There is no established safe upper limit for beets in cats, and no veterinary research defines a toxic dose of beetroot or beet greens for cats. That means any feeding advice is based on general principles, not on a specific measured threshold. Individual cases need a veterinarian who can look at your cat's full history, diet, lab work, and urine results.
Contact your veterinarian the same day if your cat ate raw beet greens in any significant amount, ate a seasoned or pickled beet product, or has vomiting or diarrhea that lasts more than a few hours.
Go to an emergency clinic now if your cat is straining to urinate, crying while urinating, producing no urine, breathing hard, collapsing, or has a swollen painful belly.
Schedule a routine visit if your cat has a history of calcium oxalate stones, kidney disease, or urinary blockages and you want to talk about diet and treat choices. Your veterinarian can review your cat's urine specific gravity, sediment, and bloodwork and tell you whether any table food is appropriate at all.
Frequently Asked Questions
Can cats eat beetroot every day?
No, beetroot should not be a daily food for cats. It offers no nutritional benefit a cat needs, and daily treats crowd out balanced commercial food. Keep it to an occasional pea-sized piece, if you offer it at all.
Are beet greens toxic to cats?
Beet greens are not classified as toxic, but mature leaves contain oxalic acid [1]. That makes them a poor choice, particularly for cats with urinary or kidney disease. The safe move is to skip the greens entirely.
Does cooking beets remove oxalates?
Cooking reduces oxalate somewhat because some leaches into the cooking water, but it does not remove it completely. There is no reliable home method to make beet greens oxalate-free. If oxalate is a concern for your cat, do not feed the greens in any form.
Can beets help my cat's urinary health?
No, there is no evidence that beets prevent or treat urinary problems in cats. Increasing dietary potassium has been shown to raise urine production and lower urine specific gravity in cats [2], but that was done with controlled supplementation, not with table food. Urinary diets are designed by veterinarians for that purpose.
What vegetables are safer for cats than beets?
Cooked carrots, plain cooked green beans, and small pieces of cooked winter squash are common choices, though all are optional treats. Cats do not need vegetables at all.
