Why is my cat's ear suddenly swollen and puffy, and should I worry since it's three times its normal size?

Yesterday afternoon, I noticed my cat's ear looking swollen and puffy, and by this morning it's grown to about three times its usual size. There haven't been any noticeable injuries or changes in her behavior, but the size difference is alarming. Should I be worried about this sudden swelling, and what might be causing it?

Answer

It sounds like your cat might be experiencing an ear hematoma. Although your cat hasn't shown signs of injury or behavior changes, quick swelling like this is concerning and usually indicates an underlying issue.

  • This could be a hematoma caused by blood vessel breakage in the ear.
  • The hematoma is often a result of scratching or head shaking due to an ear infection or allergy.
  • A prompt veterinary examination is highly recommended to address the swelling and underlying cause.

It's understandable to feel worried when you notice such changes in your cat. An ear hematoma happens when blood pools in the ear flap, often due to excessive scratching or shaking of the head. This behavior might be triggered by ear infections, mites, or allergies. While the swelling itself isn't life-threatening, the discomfort it causes to your cat is a concern, and untreated ear infections can lead to more severe complications. It's best to have your cat checked by a vet to alleviate any pain and to treat the root cause.
