Can cats eat Baking soda?
Caution. A tiny amount of baking soda (bicarbonate of soda) accidentally licked isn't a crisis. Larger ingestions cause serious sodium toxicity — it's almost pure salt, and cats are very sensitive to sodium.
If your cat has eaten baking soda
- Move your cat away from the baking soda.
- Don't induce vomiting at home — this is dangerous in cats.
- Call your vet or out-of-hours emergency vet immediately.
- If you can't reach a vet, call the Animal PoisonLine on 01202 509000 — 24/7, charges apply.
- Note how much baking soda was eaten, when, and your cat's weight.
What's the full picture?
Sodium bicarbonate is around 27% sodium by weight. A teaspoon contains over 1000 mg of sodium — more than 25 times a 4 kg cat's safe daily intake.
The usual exposure is a spilled container in the kitchen, or a baking accident. Cats rarely seek it out, but will sometimes investigate a fine powder on the floor.
Baking powder (baking soda + acid + filler) is similar-risk. Old-wives-tale uses of bicarbonate for bee stings, cleaning, etc. don't justify feeding to cats.

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.
