It's true that motion sickness in cats can cause vomiting, but they usually recover within one or two hours. If the cat is in poor health, it may take longer. You can let the cat rest in a well-ventilated place for a while and give it some glucose.



If your cat is vomiting frequently, it may be due to gastrointestinal upset or medication irritation. It's recommended to avoid giving your cat any medication initially, and observe it by withholding food for several hours. You can give it some warm water and glucose, and closely monitor its condition. If the vomiting stops, you can feed it some liquid food. If the test results indicate that the vomiting is caused by medication irritation, it's recommended to treat the cat with injections and avoid giving it any more irritating medications.
