Can cats eat butter?

Best avoided. Butter is nearly pure milk fat and salt with no benefit for a cat. A lick is not toxic, but the fat can cause stomach upset or, over time, contribute to weight gain and pancreatitis, and the dairy may not sit well. There is no reason to feed butter.

Why this answer

Butter is concentrated dairy fat, often salted, with essentially no protein or useful nutrients for an obligate carnivore. A cat's digestive system handles a sudden load of fat poorly, which can bring on vomiting, diarrhea, or a bout of pancreatitis, and the residual lactose can upset a lactose-intolerant cat. Regular buttery foods also add empty calories that push a cat toward obesity.

Watch for

  • Vomiting or diarrhea
  • Greasy or loose stool
  • Lethargy or abdominal discomfort
  • Weight gain with repeated exposure

How much is okay

None recommended; butter has no place in a cat's diet, and a stray lick needs only monitoring, not a measured serving.

Serve it safely

  • Keep butter dishes and buttery foods off counters and tables.
  • Do not use butter to coat pills or flavor a cat's food.
  • Wipe up spills so a cat cannot lick greasy residue.
