Can cats eat Salt?
No. Large amounts of salt — crisps, salted nuts, rock salt, bath salts, play dough — cause dangerous sodium imbalance in cats.

If your cat has just eaten salt
- Note what was consumed and roughly how much.
- Make fresh water freely available but don't force drinking.
- Call your vet — rapid rehydration needs to be controlled in a clinical setting.
- If you can't reach your vet, call Animal PoisonLine (01202 509000) — paid triage, 24/7.
What's the full picture?
Cats need a tiny amount of sodium in their diet, which their normal food provides. Excess salt causes cells to lose water, raising blood sodium and leading to thirst, vomiting, tremors, and in severe cases seizures and neurological damage.
Common exposure routes include crisps, salted snacks, stock cubes, gravy granules, rock salt used on icy paths in winter (cats can lick their paws after walking through it), homemade play dough, and bath salts.
Dehydrated cats, kittens, and elderly cats are at higher risk from smaller doses.

Questions owners ask
My cat licked a crisp. Do I need to worry?
One licked crisp is very low risk. A whole bag or a significant amount of salted snack warrants a vet call, especially for a small or unwell cat.
A cat water fountain encourages drinking, which supports the kidneys — worthwhile for any cat that's had a dietary scare.

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.
