If your cat is exhibiting signs of illness or injury, it is important to take them to the veterinarian as soon as possible. Before taking your cat to the vet, make sure to observe any changes in their behavior and take note of any symptoms they may be exhibiting. If possible, try to take a sample of any discharge or vomit with you to the vet. Make sure to provide your vet with a detailed history of your cat's health and any recent changes in their behavior.
