If your cat is feeling sick, they are likely to show some of the following symptoms:

  • Licking their lips and swallowing more than usual
  • Drooling
  • Eating grass
  • Reduced appetite

When to contact your vet

It may not be necessary to see your vet each time your cat vomits (most cats vomit from time to time), but it is important to monitor them and call your vet for advice if they vomit more than once, seem unwell, or have any other symptoms. Contact your vet straight away if your cat has been vomiting for more than 24 hours, is unable to keep food or water down, is very young or old, is otherwise unwell, or has any of the following symptoms:

Treatment

If your cat has vomited, but is otherwise well, you may want to try monitoring them at home before seeing a vet. Feed them normally, make sure they have access to fresh water and watch them closely. If, at any point, they appear unwell or vomit again, contact your vet. The treatment your vet gives will depend on what is causing your cat to vomit. Very mild cases may not need treatment, but if your cat has something more serious wrong they may need some investigations and treatment.
