It happens on a hot afternoon. You put a cup of gelato on the coffee table, turn away for a moment, and your cat is licking the spoon. For most plain flavours this means a possible tummy upset rather than an emergency. The flavour matters, though, and a few common gelato flavours are worth a phone call.
Key takeaways
- Gelato is usually made with milk, cream and sugar. Many adult cats do not digest dairy well and may get diarrhoea.
- A small lick of a plain flavour such as vanilla or fior di latte is unlikely to cause more than a mild upset.
- Chocolate, coffee, rum and raisin, and nut flavours carry extra risks.
- Sugar-free or diet gelato may use sweeteners. Check the label for xylitol.
- Call your vet or the Animal Poisons Helpline on 1300 869 738 if your cat ate a risky flavour or a large amount.
Why dairy is a problem for many cats
The ASPCA explains that pets do not have significant amounts of lactase, the enzyme that breaks down lactose in milk, so milk and dairy products can cause diarrhoea and other digestive upset. The RSPCA advises against giving cats milk.
Gelato is also sweet and rich, and frequent treats add calories that many indoor cats do not need. Cornell's Feline Health Center recommends keeping treats to 10 to 15 percent of daily calories.
Flavours that need more care
Chocolate and gianduja
Chocolate contains theobromine and caffeine. The Merck Veterinary Manual notes that signs of chocolate poisoning usually appear within 6 to 12 hours and can include vomiting, diarrhoea, restlessness, a fast heart rate, tremors and seizures. The darker the chocolate, the more of these compounds it contains. A chocolate gelato or one with chocolate pieces is worth a call. See our guide to chocolate and cats.
Coffee, espresso and affogato
Coffee contains caffeine. Pet Poison Helpline notes that dogs and cats are more sensitive to caffeine than people, and signs can include hyperactivity, vomiting, heart rhythm changes, tremors and seizures. Affogato, with a shot of espresso poured over, is a bigger concern than a coffee-flavoured scoop.
Rum and raisin
This flavour combines two concerns. Raisins are dried grapes, and grapes, raisins and sultanas are on the RSPCA list of foods to avoid for cats. The evidence in cats is limited. A study by the Dutch Poisons Information Center described 13 cats exposed over one year, and only two developed signs, which were mostly vomiting and other gut upsets, with no kidney injury. Because the risk cannot be ruled out, vets still treat it seriously. Some rum and raisin recipes also contain alcohol, which the ASPCA lists as a food to keep away from pets. Read more in our raisins guide.
Pistachio, hazelnut and other nut flavours
Nuts are on the RSPCA list of foods for cats to avoid. The ASPCA notes that nuts are high in oil and fat and can cause vomiting and diarrhoea. The RSPCA list names macadamia nuts specifically, so mention them to your vet if they were in the flavour. Whole nuts can also be a choking or blockage risk.
Sugar-free gelato
Some sugar-free products use xylitol, which is dangerous for dogs. A small study in six healthy cats did not find toxic effects, so the evidence in cats is limited rather than reassuring. If the label lists xylitol, call your vet. See our xylitol guide.
Signs to watch for
- vomiting or diarrhoea
- gassiness or a gurgling tummy
- restlessness, a racing heart or panting (possible chocolate or caffeine)
- wobbliness or unusual sleepiness (possible alcohol)
- tremors or seizures
What to do now
- Check the flavour and keep the tub or label.
- Estimate how much your cat ate.
- For chocolate, coffee, rum and raisin, nut or xylitol-sweetened gelato, call your vet or the Animal Poisons Helpline on 1300 869 738.
- Do not make your cat vomit at home unless a vet or the Helpline tells you to.
- For a lick of a plain flavour, offer water and watch for a tummy upset over the next day.
When to see a vet urgently
- tremors, seizures or collapse
- a racing heart, panting or extreme restlessness
- repeated vomiting or diarrhoea, or your cat seems flat
Safer ways to treat your cat
- a small piece of plain cooked chicken or fish
- freeze-dried meat treats made for cats
- a lick mat with your cat's usual wet food
FAQ
Is lactose-free gelato safe?
It avoids the lactose problem, but it is still rich and sweet. Check the flavour and ingredients, and keep it to a lick at most.
What about sorbet?
Sorbet is dairy-free, but it is sugary and fruit-based. Check that it does not contain grapes or xylitol.
My cat ate gelato and has diarrhoea. What should I do?
Offer water and call your vet if diarrhoea continues past a day, your cat vomits repeatedly or seems unwell. See our guide to vomiting and diarrhoea in cats.
