Should I Take My Cat to the Vet?

If your cat has minor symptoms, you may be wondering if a trip to the vet is necessary. While symptoms such as lack of appetite can indicate a serious problem, cats occasionally experience one or two symptoms that seem to disappear on their own without treatment. Just like humans, cats can have bad days where they simply don't feel well. Knowing when to make the trip to the vet or rush your pet to an emergency office can impact your cat's chances for survival.

  • Lethargy: If your cat has been extremely lethargic for more than a few hours, refuses to play with her favorite toys or respond to your attention, it is time for a trip to the vet to make sure there isn't a serious underlying illness.
  • Vomiting and Diarrhea: If vomiting and diarrhea go on for more than 24 hours, it is time to take a trip to your regular veterinarian. One of the biggest concerns with ongoing vomiting or diarrhea is that your cat may become dehydrated; this can cause other serious health concerns.
  • Convulsions: If your cat has any type of seizure, take him or her immediately to your nearest vet's office or emergency medical center. Convulsions can be a sign of many different illnesses. The vet can give your cat medication to help prevent another seizure and monitor your cat for additional attacks. He or she will likely run a full blood panel to try to find the root cause of the seizure.
  • Yowling: A cat that goes from room to room or follows you yowling may be in distress and trying to communicate this with you. You know your cat better than anyone else and if this is unusual behavior, keep a close eye on your pet for other symptoms that might warrant medical intervention.
