If your cat develops an ear hematoma, you may be concerned and wonder how to help. In this post, our Capitola vets discuss what causes aural hematomas in cats, in addition to symptoms and treatment options.
A pocket of blood called a hematoma can form within an organ or tissue. This is sometimes referred to as a 'blood blister' and can vary in location and size. However, in the case of aural (ear) hematomas, these appear between the cartilage and skin of your cat's ear flap.
While they don't occur often in cats, this makes it all the more imperative for cat owners to understand how to recognize ear hematomas and what to do if their feline friend develops one.
What causes aural hematomas in cats?
Typically, the cause of a cat's ear hematoma will be related to injury or trauma. When the small blood vessels located in the cat's ear flap are damaged, they break and leak internally, resulting in a blood-filled pocket or swelling. Some common causes of cat ear hematomas include:
Ear Scratching or Head Shaking
A cat may scratch their ears or shake their heads due to ear mites, infection in the ear, a foreign object caught in the ear canal or skin allergies.
Bites or Scratches
Fights with other cats or sharp thorns can leave bite or scratch marks on the ear. Underlying health issues may also be to blame.
Signs of Ear Hematoma in Cats
If your kitty as an ear hematoma, the most common symptom will probably be a new bump or swelling on the ear. If it's large enough, the ear flap itself will be swollen, potentially causing the ear flap to droop under its weight.
You may notice that the swelling feels squishy or tight, but be gentle - your cat will likely voice their displeasure if the spot is tender. In addition to changes in the appearance of your cat's ears, monitor their behavior. If they've got a tender or irritated ear, your kitty may groom the spot more than usual or shy away from touch.
Diagnosis & Treatment of Ear Hematomas in Cats
Your feline friend's ears can be closely examined by your veterinarian for infections or ear mites - common causes of hematoma aside from injury to the area. This is especially true if your cat is susceptible to infections.
Your vet may also take a sample of the hematoma using a needle to confirm the nature of your cat's condition.
Treatment: Aural Hematoma Surgery for Cats
When it comes to treating aural hematomas in cats, surgery is often recommended. The vet will make a small surgical incision in the ear flap so the blood pocket can be drained. Tiny sutures will then be used to close the pocket and to stop blood or infection from accumulating again.
To further ensure blood doesn't build up on the site, the vet or veterinary surgeon will bandage the ear.
If the hematoma on your feline companion's ear is small or your kitty cannot safely undergo anesthesia, your vet may choose to recommend draining the site with a needle.
While this will be an option to treat some hematomas, it isn't ideal and the problem is likely to return. Aural hematomas in cats can typically be effectively treated with surgery - a permanent solution to the problem. Having hematomas surgically removed can also reduce scarring.
Your veterinarian will also treat the underlying cause of the hematoma (e.g. allergy or infection).
What happens if you leave a cat ear hematoma untreated?
While ear hematomas will drain, heal and scar on their own this is not recommended. If left untreated, the following may occur:
- The ear hematoma may cause swelling while healing, which can be very painful for cats
- The ear flap may swell and prevent you from being able to treat any infection that might be present.
- It may take a very long time for ear hematomas in cats to heal on their own.
- There is an increased possibility of ear hematomas reoccurring if left to heal on their own.
- If an ear hematoma heals naturally, there is a higher risk for excess car tissue.
If your cat is suffering from an ear hematoma, it's best to have it examined by one of our veterinarians in Capitola and treated with surgery to decrease pain, speed healing and prevent the condition from reoccurring.
How much does cat ear hematoma surgery cost?
The cost of ear hematoma surgery for cats will vary based on the precise nature of the condition, your location and vet's practice, and other factors. Your veterinarian will be able to provide a cost estimate for the procedure and address your questions and concerns regarding the surgery.
Your cat could feel some amount of tenderness or discomfort for a few days following the procedure, but your vet is sure to provide medications to address pain and prevent infection and inflammation.
Your cat will need to wear a cone to stop them from scratching or rubbing the surgical site and causing inflammation, bleeding, pulled stitches, or infection.
You will receive instructions and helpful advice from your vet on how to administer home care for your feline friend as they are recovering from surgery at home, as well as when to return for follow-up visits and to have the stitches removed.
