Cat health
A cat who scratches one ear more than the other may have irritation, debris, pain, mites, infection, or skin trouble. You should worry sooner if there is odor, discharge, head tilt, swelling, bleeding, or balance change.
One-sided ear scratching is worth taking seriously because the outside of the ear can look almost normal while the canal or skin is uncomfortable.
Look from the outside for redness, swelling, odor, crust, discharge, scratches, or a greasy look. Do not dig into the ear canal or use random drops.
Treat symptom pages as triage support, not a diagnosis. Appetite, water, urine, stool, breathing, mobility, gums, pain signs, and energy matter more than one isolated symptom word.
Head shaking, a head tilt, wobbling, sudden sensitivity, or hiding after ear touch should move the question toward a veterinarian call. Ear pain can make a gentle cat react fast.
Start by deciding whether this can wait. Breathing trouble, urine changes, appetite loss, severe pain, collapse, toxin exposure, or sudden decline means the next step is a vet call.
New grooming products, cleaners, plants, dust, fleas, rough play, or a recent bath can all belong in your notes. The trigger does not replace care if scratching keeps repeating.
Write down timing, frequency, appetite, litter use, breathing, movement, and any trigger you saw. A short video is often more useful to your veterinarian than a long description.
Wipe only the outer ear if your veterinarian has shown you how and your cat is comfortable. Skip cotton swabs, deep cleaning, and leftover medicine from another pet.
Do not monitor at home when breathing is hard, gums look pale or blue, the cat cannot stand, pain is obvious, appetite stops, urination changes, or symptoms escalate.
Call your veterinarian for strong odor, discharge, swelling, bleeding, head tilt, balance trouble, repeated scratching, pain, or a cat who seems unwell. Ear problems can worsen when they are treated blindly.

Yes, if it repeats or comes with odor, discharge, swelling, head shaking, head tilt, balance trouble, bleeding, or pain.
Do not use random drops or leftover medicine. Ask your veterinarian what is safe for your cat and the actual ear problem.
