Will a Cat Ear Hematoma Go Away on Its Own? Vet-Reviewed Facts & FAQ

Share

Cat with Aural Hematoma

An ear hematoma is a blood-filled swelling in the ear flap, also known as a pinna. Most ear hematomas are a result of an underlying problem, such as an ear infection, ear mites, or skin disease, which causes the cat to repeatedly shake their head or scratch their ear. Small hematomas could go away on their own, but in most cases, these swellings are uncomfortable to the cat and cause further irritation, so veterinary attention is required. This article answers your questions about these troublesome swellings!

How Do Cats Get Ear Hematomas?

Most ear hematomas are caused by scratching or head shaking due to an underlying infection, allergy, or irritation. Cats with a bleeding or clotting disorder may also develop an ear hematoma with or without trauma, but this is a less common cause.

What Are Some Common Symptoms of Cat Ear Hematomas?

When the ear flap is full of blood, it appears swollen and may cause your cat’s ear to droop. The swelling may involve the entire ear flap or just one area. It can be hot to touch and is often uncomfortable. Some cats may shake their head or hold that ear down to one side.


Are Cat Ear Hematomas Contagious?

Cat ear hematomas are not contagious. However, if your cat has an infection or underlying condition, such as ear mites, there is a chance that it could be contagious to other cats.

Will a Cat Ear Hematoma Go Away on Its Own?

If your cat’s ear hematoma is small and painless, it may go away on its own. However, in most cases, treatment will be needed. It is important to take your cat to your vet for diagnosis and to decide on the best treatment plan.

How Can I Tell the Difference Between a Cat Ear Hematoma and an Ear Infection?

What Can I Do to Help an Ear Hematoma?

If your cat has a hematoma on their ear, it is important to take them to the vet as soon as possible. Your cat may need their ear drained, pain relief, and treatment for any underlying cause. Sometimes surgery is required. When it has healed, you should check their ears regularly to ensure that the hematoma does not recur.
