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.

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.

Questions owners ask
How much baking soda is actually dangerous to a cat?
A tiny amount licked incidentally from a spill is unlikely to be an emergency, but a teaspoon or more contains over 1000mg of sodium — more than 25 times a 4kg cat's safe daily intake — so a genuine mouthful from a container or baking accident is a real sodium-toxicity risk, not just an upset stomach.
Is baking powder as risky as baking soda for cats?
Broadly similar, yes — baking powder is baking soda combined with an acid and a filler, so it carries much the same sodium-related risk in a comparable quantity. Neither should be used as a home remedy for a cat (for bee stings, upset stomach, or anything else); if your cat has genuine digestive issues, that's a vet visit, not a bicarbonate dose.
Are there safe alternatives to bicarbonate of soda for home remedies people sometimes use on cats?
There generally isn't a safe home-remedy substitute worth reaching for — for genuine concerns like insect stings, mild digestive upset, or odour control, ask your vet for an appropriate product rather than using kitchen bicarbonate, which carries a real sodium-toxicity risk in the quantities sometimes suggested online.

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.
