PetMD guide draws a clearer line on cleaning cats’ ears
Bottom line
Most healthy cats don’t need routine ear cleaning, but PetMD’s new consumer-facing guide lays out when at-home cleaning is appropriate and when pet parents should stop and call a veterinarian. The article, written by Jennifer Grota, DVM, advises checking ears regularly for wax, debris, odor, redness, swelling, discharge, pain, or itching, and recommends cleaning only ears that appear dirty but not inflamed or painful. Its step-by-step instructions center on a vet-approved ear cleaner, gentle massage of the ear base, allowing the cat to shake, and wiping only the visible ear flap and canal opening with gauze or cotton, while avoiding cotton swabs, hydrogen peroxide, alcohol, and other home remedies.

Why it matters: For veterinary teams, the piece reflects a familiar but important preventive-care message: ear cleaning is not a universal grooming task in cats, and inappropriate home care can worsen disease or delay diagnosis. Merck Veterinary Manual notes that healthy cats generally don’t need routine ear cleaning, and that signs such as head shaking, odor, redness, swelling, discharge, or pain warrant veterinary evaluation because underlying causes can include parasites, allergies, foreign material, polyps, or infection. Merck also cautions that some cats need sedation or anesthesia for a proper otoscopic exam and cleaning when ears are painful or obstructed, underscoring the clinical opportunity to steer pet parents away from DIY treatment and toward earlier workups.

What to watch: Expect continued client education around ear-care triage, especially distinguishing simple wax removal from cases that need cytology, otoscopy, mite treatment, or investigation of allergic or obstructive disease. (merckvetmanual.com)
PetMD has published an updated how-to guide for cleaning cats’ ears at home, aimed at helping pet parents handle minor debris safely while recognizing situations that need veterinary care. The article, by Jennifer Grota, DVM, says most cats do not need frequent ear cleaning, but their ears should be checked routinely, and it draws a firm line between uncomplicated wax buildup and ears that are painful, red, swollen, odorous, or producing discharge. In those cases, PetMD advises against home cleaning and recommends prompt veterinary evaluation instead. (petmd.com)
That framing aligns with broader veterinary guidance. Merck states that healthy cats generally do not need routine ear cleaning unless a veterinarian recommends it, and that otitis externa in cats can stem from parasites, foreign bodies, allergies, bacteria, yeast, middle ear disease, or obstructive lesions such as polyps or neoplasia. Cornell’s feline health resources also emphasize that ear mites remain an important cause of feline ear disease and that cleaning may be part of treatment, not a substitute for diagnosis.

PetMD’s practical instructions are straightforward: use a veterinarian-approved ear cleaner, restrain the cat gently, apply cleaner either from a saturated cotton ball or directly into the ear canal, massage the base of the ear, let the cat shake, then wipe away loosened debris from the ear flap and visible canal with gauze or cotton. The article specifically warns pet parents not to use cotton swabs, which can push debris deeper or injure the eardrum, and not to use hydrogen peroxide or alcohol because of the risk of irritation and tissue damage. Similar advice appears in VCA’s client education materials, which endorse a “no-pour” cotton-ball technique for animals that resist liquid being squeezed directly into the ear. (petmd.com)
The stronger clinical message is in what not to do. PetMD says home cleaning should be avoided if infection or injury is suspected. Merck similarly warns against home remedies such as hydrogen peroxide or vinegar and notes that discharge and wax can reduce the effectiveness of topical therapy, meaning veterinary cleaning may be needed before treatment can work. In painful or heavily obstructed ears, cats may require sedation or anesthesia for adequate examination and cleaning. (petmd.com)
Industry reaction was limited, but the guidance is consistent with mainstream small-animal practice education: use vet-recommended products, avoid blind instrumentation, and focus on visible debris rather than deep cleaning. Merck’s professional manual adds nuance that can matter in recurrent otitis cases, including cleaner selection based on exudate type and tympanic membrane status. For example, if the tympanic membrane is ruptured, harsher cleansing agents are contraindicated and milder options such as saline or tris-EDTA are preferred. (merckvetmanual.com)
Why it matters: For veterinary professionals, articles like this can reduce low-value home interventions while improving triage. The practical upside is better-informed pet parents who understand that routine ear cleaning is not automatically necessary in cats, and that “dirty ears” can signal mites, allergic otitis, infection, or obstructive disease rather than simple grooming neglect. That can support earlier exams, cytology, otoscopy, and treatment-plan adherence, especially in recurrent cases where compliance and correct cleaner choice are central to outcomes. AAHA’s allergic skin disease guidance also notes that allergic otitis externa is a common manifestation of allergy in cats, reinforcing the need to view recurrent bilateral ear disease as a dermatologic problem, not just a cleaning issue.

There’s also a communication opportunity here. PetMD’s article gives clinics a ready-made framework for client handouts or discharge instructions: check ears regularly, clean only when advised or when mild debris is present without pain, use a vet-approved product, avoid Q-tips and home remedies, and seek care if debris recurs or the cat is scratching or shaking its head. Because many cats resist ear handling, the emphasis on gentle restraint, short sessions, and positive reinforcement may also help clinics coach pet parents more effectively. (petmd.com)
What to watch: Expect veterinary teams to keep refining client education around when ear cleaning is preventive care, when it’s part of a prescribed treatment plan, and when it risks masking a more serious diagnosis, particularly in cats with recurrent otitis, suspected mites, allergy, or unilateral disease.
