Cat Ear Hematoma Surgery Aftercare: Collar Time, Stitches and What's Normal

After cat ear hematoma surgery, keep a recovery collar on for 10 to 14 days so your cat cannot scratch or shake the ear, give all medication on schedule and keep the ear clean and dry. Some bruising is normal; swelling that refills, discharge or an ear held at an odd angle needs a vet recheck.

An ear hematoma is a pocket of blood between the skin and the cartilage of the ear flap. In cats it almost always follows head shaking or scratching, which is why the cause behind it, such as ear mites, an infection or allergies, matters as much as the surgery. Here is how recovery works.

What does cat ear hematoma surgery recovery involve?

The vet drains the blood and closes the space, often with sutures through the ear flap or a small drain, and sometimes a light bandage. Most cats go home the same day. You will usually return in 10 to 14 days to remove stitches and check the ear.

For those two weeks, your job is to stop the ear from being scratched, shaken or rubbed. Every flick of the head can make the pocket refill, and every claw can open the stitches. Our dog-focused ear hematoma aftercare guide covers a similar timeline, though cats are more agile at reaching the ears.

Does my cat need a recovery collar after ear surgery?

Yes, in almost every case. Cats can reach the ear with a hind paw faster than you can react, and itchy stitches make them try. The collar blocks that reach. Ask your vet which style they prefer for an ear procedure, since a bandaged ear changes the fit.

An inflatable collar works for many cats because it sits snug around the neck and stops a hind paw from reaching up to the ear, without limiting their view the way a hard cone can. Check the fit with the two-finger rule. For cats that wiggle out of everything, see why a cat's recovery collar keeps coming off.

What is normal after cat ear hematoma surgery?

These are common in the first week:

Mild swelling and bruising on the ear flap, purple or yellow in tone.

A small amount of dried blood or clear fluid near the stitches.

An ear that sits slightly lower or looks thicker than the other.

Sleepiness for the first 24 hours after anesthesia, and a smaller appetite that returns by the next day.

Call your vet if you see:

The ear filling again with fluid or blood, or swelling that gets bigger after day 3.

Yellow or green discharge, a bad smell or heat from the ear.

Stitches pulled out, or your cat tilting the head constantly.

Loss of balance, circling or very dull behavior. See why a cat may be wobbly after surgery for the difference between anesthesia effects and a problem.

Why did my cat get a hematoma in the first place?

The surgery fixes the pocket, not the cause. The usual triggers are ear mites, ear infections, allergies and foreign material in the ear canal. Ask your vet to examine and treat the canal at the same visit. If the underlying itch continues, the hematoma can come back, even after a good repair.

How do I give ear medication to a cat in a collar?

Many vets prescribe ear drops or oral antibiotics. Work in a small room and wrap your cat in a towel with the head free. Keep the collar on and lift the ear flap gently while placing drops at the canal opening, then massage the base of the ear for 10 to 15 seconds. Reward with a small treat. If giving medicine is a struggle, read how to give a cat medication after surgery.

How do I keep my cat calm for two weeks?

A calm cat shakes the head less. Keep your cat in one quiet room with a litter box, food, water and a bed, away from other pets, for the first 3 to 5 days. Use a lamp or radio at a low level, and limit jumping. See how to keep a cat calm after surgery and how to keep a cat from jumping.

Cat ear hematoma aftercare FAQ

Can I clean the ear myself?

Only if your vet says so. Wipe visible dirt on the outer flap with a damp cotton pad, and do not put anything into the canal unless prescribed.

How long until the ear looks normal?

Swelling usually settles within 2 to 4 weeks. Some cats keep a slightly crinkled or thickened ear flap, which is cosmetic.

Can my cat go outside afterward?

Not until the stitches are out and the ear has healed. See when a cat can go outside after surgery for the general timing.

What if my cat sneezes or shakes the head?

An occasional shake is normal. Persistent shaking means pain or itch; call your vet. See why a cat may sneeze after surgery.
