Can cats eat potatoes?
Last updated 2026-05-08 · Sourced from ASPCA & Merck Veterinary Manual
The short answer
Sometimes — with caution — cats should only have small amounts of potatoes. Plain cooked, tiny Starchy tuber, base of many cuisines.
Remember: cats are obligate carnivores. They derive almost all their nutrition from animal protein, so even "safe" plant foods are treats — not staples.
Why be careful
Plain cooked potato is non-toxic but offers no nutrition for cats.
What every cat owner should know
- No raw or green
- No butter/dairy mash
What to do if your cat ate potatoes
- Stay calm. Note how much was eaten and when.
- Call your vet or ASPCA Animal Poison Control at 888-426-4435.

- Do not induce vomiting in cats unless instructed by a vet — it's risky.
- Bring product packaging to the vet visit.
Kitten safety
Generally avoid feeding potatoes to kittens. Their digestive systems are still developing and they're more sensitive to changes in diet, fat, sodium, and lactose than adults. If you've already given some, watch for vomiting, diarrhea, or lethargy and contact your vet if any appear.
What to do if your cat ate potatoes
- Note how much was eaten and when. A small amount is rarely an emergency, but a large quantity may need vet attention.
- Watch for symptoms over the next 12–24 hours: vomiting, diarrhea, lethargy, loss of appetite, or changes in drinking/urination.
- Provide fresh water and skip the next meal if your pet seems unsettled — let their stomach calm down.
- Call your vet if symptoms appear or persist beyond 24 hours, or if the amount eaten was significant.
