Cats That Yowl, Vomit, or Soil the Carrier on Vet Trips: Car Sickness

📊 Flowchart

1. Step 1Control meals before leaving: To prevent vomiting and aspiration from car sickness, hold off on solid food starting 3–4 hours before you leave for the vet, except in emergencies (water is fine until just before you go), and let your cat use the litter box before you set off.

2. Step 2Prepare the carrier and cover it completely: Put your cat in a mesh laundry bag and place them in a hard-sided carrier (lined with two thick pee pads so they stay clean even if they have an accident), then cover the whole carrier with a large, breathable dark-colored bath towel to block the view outside completely.
   ↓
3. Step 3Position it securely in the car: Car seats slant, so a carrier set directly on them tilts and makes motion sickness more likely. Tuck a towel underneath so it sits level, then strap it in firmly with the seatbelt or place it on the floor in front of the passenger seat or back seat, where there is the least motion, and keep the car cool (22–24°C [72–75°F]) and free of fragrance.

4. Step 4For cats who vomit heavily, have accidents, or hyperventilate every time, go to the hospital without your cat before the next visit and get anti-nausea or motion sickness medication or anti-anxiety medication prescribed in advance to give at home before leaving.

❌ Never do this

• ✕Opening the carrier door and holding your cat on your lap while the car is moving because you feel sorry for them crying (a panicked cat can crawl into the driver's footwell under the brake pedal and cause a serious accident, or leap out onto the road the moment a window or door opens and be hit by a car—never do this!).
• ✕Placing a strongly scented air freshener (car deodorizer) in the car or driving with loud music (this rapidly worsens car sickness in cats, whose senses of smell and hearing are sharp).
