How much ice cream for your cat?
Most guides say "a few pieces". Enter your cat's weight and get the actual daily ceiling, worked out from ice cream's calories and the 10%-of-daily-calories treat rule vets use.
Assumes a healthy, neutered adult at a stable weight, and that this is their only treat that day. Puppies, pregnant, very active or unwell pets need different amounts — ask your vet.
Why this verdict for cats
Most cats are lactose intolerant, so ice cream commonly causes stomach upset, and the sugar is unhealthy.
On a hot day a lick of ice cream seems harmless, but between the lactose, sugar and risky flavours, it's a treat to be careful with.
How much is safe?
A small lick of plain vanilla may be tolerated, but dairy upsets lactose-intolerant pets and the sugar isn't good for them. Crucially, never give chocolate ice cream or anything 'sugar-free' (it may contain xylitol, deadly to dogs).
What happens if a cat eats too much?
Expect possible diarrhea, gas and an upset stomach from the lactose and sugar; chocolate or xylitol flavours are an emergency.
How to serve it safely
Better swaps: a spoon of plain xylitol-free yogurt, 'nice cream' made from frozen mashed banana, or just frozen watermelon chunks — cool treats without the dairy and sugar.
