Can Cats Eat Ham?
Updated 18 October 2026 · Researched against PDSA, Cats Protection and International Cat Care guidance
!Only as a treat
A small sliver of plain cooked ham is not toxic, but it is salty processed meat — an occasional taste, not a treat routine.
Ham is cooked pork that has been cured, which means salt. A cat's daily salt requirement is tiny, and a couple of slices of ham can be a meaningful load for a four-kilogram animal, especially if it happens often.
The fat content varies from lean cooked ham to fatty offcuts, and the fatty end is the one that upsets digestion. Plain, lean, cooked ham in a small piece is the only version worth considering.
What to watch for in the UK
- Honey-roast, smoked and dry-cured hams carry extra sugar or salt — read the pack.
- Christmas ham and gammon glazed with mustard or honey is not suitable for a cat.
- Processed ham slices from a packet are saltier than a joint carved at home.
- Never give the rind: it is tough, salty and hard to digest.
If your cat has already eaten it
- A small piece: nothing to do beyond offering fresh water.
- A large amount: watch for vomiting, diarrhoea and heavy drinking; phone your vet if the cat seems unwell.
Signs that need a vet, not watchful waiting
- vomiting
- diarrhoea
- increased thirst
- reduced appetite
Out of hours, use your practice's emergency number. If you can, take the packaging with you — the ingredient list often tells the vet more than the description does. This page explains risk; it cannot diagnose your cat, and it deliberately contains no doses or home treatments.
If your cat is already vomiting, see the cat vomiting guide. For the wider red-flag checklist, use sick cat symptoms. If a plant rather than a food is involved, the toxic plants checklist is the right page.
