Can cats eat Christmas ham / gammon?
No. Christmas ham is too salty for cats and often glazed with sugar, honey, or mustard. High salt and fat can cause serious problems.

If your cat has just eaten christmas ham / gammon
- Move your cat away from the ham and any remaining food.
- Don't induce vomiting at home.
- Call your vet — ham combines high salt, nitrates, and sometimes allium-containing glazes.
- If you can't reach a vet, call the Animal PoisonLine on 01202 509000 — 24/7, charges apply.
- Provide fresh water — the salt content causes excessive thirst.
What's the full picture?
Ham and gammon are cured meats, heavily salted during processing. A portion that looks small to us contains a sodium load a cat shouldn't handle.
Christmas glazes often add honey, mustard, cloves, or other spices — none of which are helpful, and cloves in larger amounts can be toxic.
A single nibble isn't usually a trip to the vet, but avoid making ham a habit.

About this guidance
Every entry on this site is compiled from published UK veterinary toxicology sources — International Cat Care, Veterinary Poisons Information Service (VPIS) references, RCVS-registered practice materials, and peer-reviewed feline medicine literature. Where the evidence is mixed, we err on the cautious side because cats are unusually sensitive to many common substances that are harmless to humans and even to dogs.
This is general information written for UK cat owners. It is not personalised veterinary advice for your specific cat, their age, weight, medical history, or the exact exposure you're dealing with. If your cat has eaten something or is unwell, call your vet first. The Animal PoisonLine on 01202 509000 is available 24/7 for a small fee and can tell you whether an emergency visit is needed.
