My 6 kg senior cat with congestive heart disease on medication just licked a small puddle of olive oil from the kitchen floor — is this a concern?

Short answer

Olive oil itself is not toxic to cats, and a small lick from the floor is unlikely to cause a serious problem. However, your cat has congestive heart disease and is on medication, so her system handles things differently than a healthy cat would. Watch for vomiting or diarrhea over the next 24 hours — if either appears, offer a bland diet and call your vet. Otherwise, no emergency action is needed, but mention the incident at her next routine check-up so her cardiologist is aware.

Olive oil — Food safety facts

A small drizzle over food is safe. Watch the calories.

Dogs and cats carry the same rating (Safe to share), so the notes below hold for either pet.

Olive oil is not toxic to cats. The real limit is calories, fat and salt, so treat it as a small extra alongside the normal ration rather than a meal in itself.

There is no poisoning risk here, and the usual problem is simply eating too much at once: a heavy fat or salt load can bring on loose stools or a single vomit. Offer water, keep an eye on the pet for 24 hours, and do not induce vomiting.

Olive oil can stay on the rotation, but only as an extra mouthful: keep the rest of the day's food unchanged and watch the litter box and how quickly they finish the next meal.
