Can cats eat Biscuits?
No. UK biscuits usually contain multiple things cats can't have — chocolate (Digestives, chocolate biscuits), raisins (garibaldi, fruit shortcake), and always too much sugar and fat. Treat a biscuit theft as a potential poisoning.

What's the full picture?
A surprising number of common UK biscuits contain at least one outright toxin: chocolate coatings, chocolate chips, raisins, sultanas, or currants. Digestives, custard creams, and plain rich tea are the least risky, but still bad for cats.
Even 'safe' biscuits are packed with sugar, fat, and salt that cats don't handle well. Regular biscuit-sharing leads to obesity, dental issues, and diabetes risk.
If your cat has stolen a biscuit, identify the type. Any chocolate content, raisins, or 'dried fruit' means call your vet. Plain biscuits mean monitoring for GI upset.

Questions owners ask
How can I tell if a stolen biscuit is a genuine emergency?
Identify the type before deciding. Any chocolate coating or chips, or any raisins, sultanas, or currants (as in garibaldi or fruit shortcake biscuits), means calling your vet or the Animal PoisonLine straight away. Plain biscuits like digestives, rich tea, or custard creams are lower risk and mainly call for monitoring for sugar- and fat-related GI upset over the following day.
How long until symptoms show if the biscuit did contain chocolate or raisins?
For chocolate-containing biscuits, expect possible vomiting and restlessness within 6 hours, potentially progressing over 12–72 hours in larger exposures. For raisin-containing biscuits, kidney injury signs — reduced urine output and lethargy — typically develop over 12–72 hours after initially normal-looking behaviour. Don't wait for the delayed signs to appear before calling your vet; call as soon as you've identified the ingredients.
Are there safe biscuit-like treats I can give my cat instead?
Commercial cat treats and biscuits are formulated specifically for feline nutrition and don't carry the chocolate, raisin, sugar, or salt risks of human biscuits. If your cat enjoys the crunch of a biscuit, a cat-specific dental treat or biscuit satisfies that without the ingredient risks.
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.
