Cats experience nausea for a variety of reasons, including change in diet, motion sickness or a serious disease such as kidney failure or inflammatory bowel disease. Symptoms of nausea include drooling or salivation, excessive whining or crying, and of course, vomiting. It is always best to consult your veterinarian about any medical problem your cat experiences, however, there are a few strategies you can try at home to make your cat more comfortable.
Observe your cat's symptoms, and make a note of them. Your veterinarian needs this information to properly diagnose and set up a course of treatment for your cat.
Contact your veterinarian. Inform the vet of your cat's problem and symptoms. If the problem is severe, your veterinarian will ask you to come in immediately. If the problem is less severe, you can set up an appointment for a check-up or simply treat the nausea at home.
Keep an eye on vomiting. It may be disgusting, but look at the vomit and take note of the colour, contents (is your cat regurgitating food or parasites?), and frequency. Your veterinarian will need this information.
Place your cat on a fast. This involves removing all food for 24 hours, and only offering controlled amounts of water. This allows the digestive system time to heal and rest.
Offer your cat a bland diet after the fast. This consists of small amounts of boiled chicken with some boiled white rice. These foods are easy to digest and help your cat bounce back from feeling ill. They are also helpful for stopping vomiting.
Ensure that your cat stays hydrated, especially if he shows no interest in food or has been vomiting. Offer plenty of clean, fresh water or chicken broth to prevent dehydration.
Medicate your cat before car trips or stressful events (moving, house guests, storm or separation anxiety, adding a new pet or child to the home) if your cat's nausea is brought on by stress or motion sickness. Your veterinarian can provide you with a good medication or recommend one you can purchase over the counter.
Finding the underlying cause of your cat's nausea is the most important step in treatment, and this is best done by a veterinarian. Whatever the underlying cause, be sure to treat it exactly as your veterinarian recommends and inform the vet immediately if your cat's conditions worsens during treatment.
