Cats can get carsick. Symptoms of carsickness in cats may include vomiting, drooling, howling, slowed breathing, and lethargy. When a cat is carsick, its digestive system may become upset due to parasympathetic nervous system dysfunction, leading to vomiting and drooling. Some cats may howl because they are not used to riding in a car or it's their first time. At the same time, a cat's breathing may become slow or even labored due to carsickness.

If your cat is carsick, there are a few things you can do to help alleviate its discomfort. First, if possible, stop the car immediately and take your cat to a well-ventilated area to rest, or keep your cat on a leash and open a window for ventilation. Second, you can give your cat a small amount of water and canned food, but avoid feeding it shortly after it has become carsick, as this may worsen vomiting. Once your cat has recovered, place it in a spacious cage and gently pet it to soothe its anxiety.
