Can Cats Eat Potatoes?

Q: Can my cat eat sweet potato?

Cooked plain sweet potato (no skin, no seasonings) is generally safer than raw potato and may be offered in very small amounts. Sweet potato is still high in carbohydrates—treat it as an occasional treat and avoid sweetened or fried preparations.

Q: What are signs of potato poisoning in cats?

Signs include vomiting, diarrhea, drooling, abdominal pain, lethargy, weakness, tremors, and in severe cases respiratory difficulty or collapse. Contact a veterinarian or poison control hotline immediately if you suspect poisoning.

Q: Is mashed potato with milk and butter OK?

No. Dairy, butter, salt, and other seasonings increase fat and sodium, which can cause digestive upset or pancreatitis. Only plain, cooked potato without additives is acceptable as an occasional treat.

Q: How often can I give my cat potato?

If you choose to give potato at all, limit it to a rare treat (no more than once or twice a week) and keep portions very small (<10% of daily calories).

CONDITIONAL: Cats can eat small amounts of plain, cooked potato occasionally, but raw or green potatoes contain solanine and are toxic. Potatoes are high in carbs and not nutritionally necessary for cats.

Quick Safety Summary

CONDITIONAL: Plain, fully cooked potatoes (boiled or baked, no salt, butter, seasonings, onion/garlic) can be given to cats as a very occasional treat in small amounts. Raw potatoes, potato peels, green potatoes, or sprouts can contain toxic glycoalkaloids (solanine) and must be avoided—seek immediate veterinary advice if ingested.

Short verdict (first sentence)

CONDITIONAL: Cats can eat small amounts of plain, cooked potato occasionally, but raw or green potatoes are potentially toxic due to solanine and potatoes are not a necessary part of an obligate carnivore's diet.

Why potatoes are not a typical cat food

Cats are obligate carnivores: their bodies evolved to get most nutrients from animal tissue, especially protein and fat. Potatoes are starchy tubers that are high in carbohydrates and low in the key nutrients cats need (e.g., taurine, arachidonic acid, vitamin A preformed). Feeding potatoes adds calories and carbs without delivering meaningful feline-specific nutrition and can contribute to weight gain, digestive upset, or worsen diabetes in susceptible cats.

Nutritional snapshot (boiled potato, 100 g, no skin):

Calories: ~87 kcal
Protein: ~1.9 g
Fat: 0.1 g
Carbohydrate: ~20 g (mainly starch)
Fiber: ~1.8 g
Potassium: ~379 mg
Vitamin C: ~8 mg

For most adult cats, daily energy needs range ~20–35 kcal per pound depending on age, activity and neuter status. Even a small spoonful of potato can be a noticeable percentage of a small cat's treat calories.

The toxic risk: raw, green potatoes and solanine

Potatoes naturally produce glycoalkaloids (mainly solanine and chaconine) as a defense against insects and disease. Concentrations increase in:

Raw potatoes vs cooked potatoes
Green or sun-exposed potatoes (chlorophyll is visible and often accompanies higher solanine)
Potato sprouts and peels

Solanine is a gastrointestinal and neurological toxin. Signs of glycoalkaloid poisoning in cats can include vomiting, diarrhea, drooling, abdominal pain, decreased appetite, lethargy, weakness, tremors, incoordination, and in severe cases, respiratory distress or collapse. The severity depends on the amount and the glycoalkaloid concentration.

Authoritative sources list potato (raw/green parts) as a potential toxin to pets—do not feed raw or green potatoes to cats (ASPCA, Pet Poison Helpline, AVMA). If you suspect your cat ate green potato, peels, or sprouts, treat this as a potential poisoning and contact your veterinarian or a pet poison control center immediately.

Emergency steps (if raw/green potato ingestion is suspected)

Stay calm and collect what remains (piece of potato, peels, packaging) and note the amount eaten.

Call your veterinarian or a pet poison hotline right away (ASPCA Animal Poison Control: 888-426-4435 — fees may apply; Pet Poison Helpline: 855-764-7661).

Do NOT induce vomiting or give home remedies unless instructed by a professional.

If advised, transport your cat to your veterinarian or an emergency clinic quickly—bring a sample of the potato for testing if possible.

Can cooked potatoes be fed safely? How to prepare

Yes — fully cooked plain potato (boiled or baked), cooled and mashed or chopped, can be fed as an infrequent treat in very small amounts. Key preparation rules:

Cook thoroughly (boiled or baked) — cooking reduces glycoalkaloid activity and makes starch digestible.
Remove skins and sprouts completely — peels can concentrate glycoalkaloids.
No salt, butter, milk, cream, gravy, onion, garlic, chives or other seasonings (onion and garlic are separately toxic to cats).
No fried or heavily fatty preparations — fats can cause pancreatitis and add excess calories.

Suggested serving sizes (occasional treat only)

Aim for treats to be <10% of daily calories and fed no more than once or twice a week at most. Approximate guidance (boiled potato, calories based on ~87 kcal/100 g):

Cat 2 kg (4.4 lb): 1 teaspoon (≈5 g, ≈4 kcal) as an occasional nibble
Cat 4 kg (8.8 lb): 1 teaspoon–1 tablespoon (≈5–15 g, ≈4–13 kcal)
Cat 5–6 kg (11–13 lb): up to 2 tablespoons (≈30 g, ≈26 kcal) rarely

These are maximum occasional amounts — many cats won’t need or want potato. If your cat is overweight, diabetic, young, elderly, or has digestive disease, avoid starchy treats entirely.

Health concerns and when to avoid potatoes

High carbohydrate load: Cats have limited ability and need to handle large carbohydrate loads. Frequent potato treats can promote obesity and dysregulated blood glucose.
Pancreatitis risk: Avoid greasy/fried potato preparations and fatty toppings, which can trigger pancreatitis.
Allergic or intolerant cats: Some individual cats may vomit or have diarrhea after starches.
Interactions with medical diets: Cats on therapeutic diets (e.g., diabetic, renal) may need strict calorie and nutrient control—check with your veterinarian before offering new treats.

If your cat has diabetes, is overweight, or has a history of gastrointestinal disease, discuss with your veterinarian before introducing even small amounts of potato.

Safer alternatives to potatoes

If you want to offer variety or rewards, choose options that fit feline nutrition better:

Small pieces of cooked plain chicken, turkey, or fish (no bones, no seasoning)
Commercial feline treats formulated for cats (low-carb options available)
Fortified cat-safe freeze-dried proteins

Vegetable treats should be rare; cats get most vitamins and amino acids from animal sources.

Key Takeaways

CONDITIONAL: Plain, fully cooked potatoes can be offered only rarely and in very small amounts as an occasional treat.
NEVER feed raw potatoes, green potatoes, peels, or sprouts—these can contain solanine and are potentially toxic.
Potatoes are high in starch and calories and provide little of the nutrients cats need; excessive feeding can cause weight gain and metabolic issues.
If your cat eats raw/green potato, call your veterinarian or a pet poison control center immediately and follow their guidance.
