Motion Sickness in Cats
Motion sickness is one of the most common problems in cats that travel by car. It's caused by the same vestibular system disruption that causes car sickness in humans — the cat's inner ear tells them they're moving, but their eyes (often seeing only the carrier interior) don't agree.
Symptoms
- Drooling or excessive lip-licking
- Yawning repeatedly (a sign of nausea in cats)
- Vomiting
- Restlessness followed by lethargy
- Crying or meowing more than usual
Note that some of these overlap with general travel anxiety. A cat that drools and meows but never vomits may be anxious rather than nauseous — or both.
Prevention
- Withhold food for 2-3 hours before travel. An empty stomach reduces vomiting.
- Position the carrier so the cat can see out a window. Visual input that matches motion cues reduces nausea.
- Smooth driving — gentle acceleration, wide turns, avoid stop-and-go traffic when possible.
- Fresh air — crack a window slightly or use fresh air mode on the climate controls. Stale air worsens nausea.
Medication
If behavioral and environmental strategies aren't enough, your vet can prescribe maropitant (Cerenia), which is effective against motion-induced vomiting in cats. It's given as a single dose before travel. Meclizine (an over-the-counter antihistamine used for human motion sickness) is sometimes used in cats, but dosing should always be guided by your vet — don't give human medications to cats without veterinary advice.
Does It Get Better?
Often, yes. Many cats that experience motion sickness on early trips grow out of it with repeated exposure. Kittens are especially prone to motion sickness, and most improve significantly as adults. If your adult cat still gets sick after multiple trips, medication is a reasonable long-term solution.
