Raisins are dried grapes. In dogs they are a well-known cause of sudden kidney injury, sometimes after small amounts. Cats appear less often in case reports, yet that is not permission to feed raisin toast, trail mix, or fruit cake. Treat any raisin ingestion in a cat as a prompt phone call to a professional, not a social media poll.
Key takeaways
- Never offer raisins, sultanas, currants, or grapes to cats.
- Vomiting and lethargy can precede kidney problems; some pets show little warning at first.
- Call your vet or Animal Poisons Helpline (1300 869 738) with timing and amount.
- Do not induce vomiting with salt or hydrogen peroxide unless a vet or the helpline directs a specific plan.

Why raisins are a problem
A toxic principle in grapes and raisins is still researched, which is exactly why "safe dose" charts for home use are unreliable. Dried fruit packs more fruit per mouthful. Cats that steal from bags get a concentrated hit. Chocolate-covered raisins add theobromine risk on top.
Typical scenarios
- Hot cross buns and fruit loaves left on low tables
- Children's snacks in open bags
- Baking benches during holidays
- "Healthy" salad toppings knocked to the floor
Signs
Vomiting, diarrhoea, drooling, belly discomfort, quiet behaviour, reduced appetite, increased thirst or urination, and later signs of kidney injury such as continuing lethargy or changes in urine output. Trust the history even if early signs are mild.
When it is an emergency
Repeated vomiting, collapse, seizures, no urine, or severe lethargy after raisin theft: go to an emergency clinic. Take the packet.
Immediate steps
Remove access. Estimate count of raisins and time of eating. Phone your vet or 1300 869 738. Follow advice on whether to travel in now, what monitoring to do, and whether any decontamination is indicated. Do not invent doses of human medicines. Do not wait overnight "to see" if a handful went missing and your cat is a small adult or kitten.
Prevention
Store dried fruit like medication: high cupboard, latch if needed. Teach kids not to share people snacks. After parties, vacuum floors before letting cats roam.
After the phone call
Write down the advice you receive, the time, and any recommended arrival window at a clinic. If watchful waiting is suggested, log appetite, vomiting, and litter tray urine clumps through the next day and recheck if anything worsens.
Keep remaining raisins sealed so a second raid cannot happen while you are at the clinic with pet number one.
FAQ
One raisin fell and the cat mouthed it.
Still call. Professionals decide based on size, time, and details.
Are sultanas different?
Treat sultanas like raisins. Same advice pathway.
Can activated charcoal at home fix it?
Only use products and timing a vet specifies. Wrong use wastes critical minutes.
My dog ate some too.
Seek advice for each pet. Dogs have well-documented risk and often need urgent care.
Why speed matters
Toxin cases go better when the clinic knows the product name, approximate amount, and exact time. Photograph labels. Note your cat's weight if you know it. Drive safely; do not try experimental home cures on the roadside.
While waiting for advice, keep the cat calm and away from further food hazards. Separate pets so one animal's charcoal or vomit cannot be eaten by another. If you are directed to come in, bring a carrier lined with a towel and a sample of the remaining food sealed in a bag.
Prevention is dull and effective: close the pantry, teach children firm rules, and treat dried fruit and onion-family leftovers like household chemicals around pets.
Working with your veterinarian
Bring a short written timeline of what you have noticed, including dates and photos. Short videos of breathing, gait, or behaviour often help more than adjectives. Ask what should improve within 24 to 48 hours and what should trigger an earlier return.
Avoid stacking multiple new products, shampoos, or diet changes on the same day as a clinic visit; it muddies the picture. If cost is a concern, say so early so the team can prioritise diagnostics and discuss staged plans without judgment.
Talk with a vet
For rapid triage after a kitchen theft, Book a Dial A Vet consult and keep the Animal Poisons Helpline number available.
