How can I tell if my cat is sick?

If your cat is feeling under the weather they will show subtle changes in behavior and energy level, but these changes can be difficult for pet parents to detect. That's why it's important to monitor your kitty's health and watch for these signs of common and serious cat illnesses.

Is my cat sick?

Much like people cats can suddenly find themselves feeling unwell. Cat illnesses range from common and highly contagious cat colds (upper respiratory infections), to diabetes, feline immunodeficiency virus, feline leukemia virus, worms, hyperthyroidism and even cancer.

Of course, the symptoms that your cat shows will depend upon the kind of illness they are suffering from however there are a number of symptoms that are common to many health issues in cats.

Below our vets from Berkeley Dog & Cat Hospital share a few signs that can mean it's time to book a vet appointment, as well as more serious symptoms that indicate that your cat is in need of emergency veterinary care.

Signs of a Sick Cat

Cats possess a natural instinct to hide if they are sick or injured, so it's important to monitor your cat's behavior to watch for anything that seems out of the ordinary for your kitty. Although it may just be a passing bout of indigestion or a cold, it's also possible that your cat has a more serious condition that needs medical attention.
