Can cats eat Gravy?
No. Most gravy contains onion, salt, and often garlic. Gravy granules and stock cubes are particularly concentrated.

Key facts
- Verdict: No — dangerous to cats. Gravy should never be given deliberately.
- Category: UK festive
- If it's already happened: Call your vet now, or the Animal PoisonLine on 01202 509000 (24/7, charges apply) — see the emergency steps below.
If your cat has just eaten gravy
- Move your cat away from any remaining gravy. Do not try to make them vomit at home — this is dangerous in cats and rarely works.
- Note how much was eaten and when, and keep the packaging or a photo of the plant/substance if you can.
- Call your vet immediately, even out of hours. Tell them your cat's weight, what they ate, and when.
- If you can't reach your vet, call Animal PoisonLine (01202 509000) — paid triage, 24/7 for guidance. They can advise on urgency and route you to emergency care.
What's the full picture?
Home-made gravy is usually made with meat juices plus onion, plus red wine or stock. All three are problems for cats (the onion especially).
Gravy granules and OXO stock cubes are even more concentrated sources of onion powder and salt.
The cat-licks-Sunday-roast-plate scenario is one of the most common recurring low-dose onion exposures vets hear about.
Safer alternatives

Questions owners ask
Is a lick of gravy on a Sunday roast plate actually dangerous?
A single lick of gravy from a plate is unlikely to cause acute illness in a healthy adult cat, but gravy is a concentrated source of onion and salt, and the real danger is repeated exposure — a cat that regularly gets to lick the gravy off Sunday roast plates is accumulating a low, ongoing dose of allium toxin that can cause anaemia over weeks without any single dramatic incident. If plate-licking is a regular habit in your house, it's worth stopping now rather than waiting for symptoms.
Are gravy granules or stock cubes worse than homemade gravy?
Yes, generally. Gravy granules and stock cubes (including OXO cubes) concentrate dehydrated onion and garlic powder along with salt, so a small amount of granules or crumbled cube can contain a more concentrated allium dose than the equivalent volume of a slow-simmered homemade gravy. Keep both well out of reach, and treat any confirmed ingestion of dry granules or a stock cube as more concerning than an equivalent splash of liquid gravy.
How long until symptoms show after a gravy exposure?
Because gravy is an onion-family exposure, follow the same pattern as other allium toxicity: early GI signs within the first 24 hours, with the more serious anaemia signs — pale gums, weakness, dark urine — typically developing over 1–5 days as red blood cells are damaged and cleared. A single incidental lick rarely reaches this stage, but repeated exposure over several meals can.
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.
