Cat Illnesses: Signs & Symptoms

If you have a kitty who isn't feeling too well, they will display subtle, and some not-so-subtle changes in their behavior. Our Bellevue vets explain the common and more intense symptoms of 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, several symptoms are frequent to illnesses that a cat could catch.

Below, our vets from Aerowood Animal 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 an Illness

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 could require care from a veterinarian.

Cats hide pain and illnesses well, so what looks like a minor issue could be the sign of something more serious. Contact your vet to book an appointment if you notice any of the following symptoms:

  • Increased urination
  • Breathing issues, or changes in breathing
  • Runny eyes or nose, clear, green, or white
  • Excessive shedding, bald patches, skin irritation
  • Blood in the urine
  • Changes in personality - in longer playful or refuses to go outside
  • Vomiting
  • Diarrhea or constipation - especially if your cat appears to be in pain
  • Lethargy - sleeping more than usual
  • Increase or decrease in appetite
  • Weight changes - Sudden decrease or increase in weight
  • Increased thirst

Signs of a Veterinary Emergency

While the symptoms listed above indicate that it's time to book a veterinary appointment for your cat, the symptoms listed below are much more serious. If your cat shows any of the following symptoms urgent veterinary care is required.

If you are unclear whether your cat's symptoms qualify as an emergency, play it safe and contact a professional.

  • Indications of severe pain - typically accompanied by loud crying or aggression
  • Bleeding that is moderate to extreme
  • Any exposure to poison
  • Vomiting blood
  • Unresponsiveness or unconsciousness
  • Unable to walk or signs of dizziness
  • Overly high or low temperatures - under 99° or over 104°
  • Seizure
  • Trauma
  • Breathing difficulties
  • Signs of pain while urinating
