Cats may chew on metal because of curiosity, texture, teething, boredom, stress, dental discomfort, nausea, or pica-like behavior. The chewing itself is not something to ignore: metal can chip teeth, cut the mouth, expose a cat to unsafe residues, or become a swallowed foreign object. If your cat may have swallowed metal, is gagging, vomiting, drooling, not eating, painful, lethargic, or acting unwell, call your veterinarian or an emergency clinic right away.
Why metal chewing matters
A quick lick or sniff of a metal table leg is different from repeated chewing, biting, or swallowing pieces. Metal is hard enough to injure teeth and gums, and small pieces such as staples, twist ties, jewelry parts, coins, needles, screws, batteries, fishing gear, and hardware can be sharp, toxic, or obstructive if swallowed.
Do not wait to see whether a swallowed object passes if the item was sharp, magnetic, battery-like, chemically coated, or unknown. Your vet may recommend an exam, imaging, or poison-control guidance based on the object, your cat’s size, and symptoms.
Common reasons cats chew metal
Curiosity and texture. Cats investigate with their mouths. Cool, smooth, reflective, or moving metal objects can be interesting, especially if they make noise when nudged.
Teething or oral discomfort. Kittens may chew more while adult teeth come in, but adult cats can also chew oddly when their mouth hurts. Dental disease, broken teeth, resorptive lesions, mouth ulcers, or something stuck between the teeth can change how a cat chews.
Boredom or under-stimulation. A cat with too little play, climbing, scratching, hunting-style activity, or food puzzle work may create their own entertainment. For a broader behavior overview, see why cats chew everything.
Stress and displacement behavior. Some cats chew when they are anxious, frustrated, or trying to settle themselves after a change in routine, new pet, move, conflict with another cat, or lack of predictable hiding spots.
Pica-like chewing or eating. Pica means chewing or eating non-food items. In cats, repetitive non-food chewing can be behavioral, but it can also be associated with medical problems, nutritional imbalance, gastrointestinal disease, or other health issues. Similar pica-adjacent behaviors can show up as wall licking or repeated fabric chewing, such as when cats knead and bite blankets.
When to call a veterinarian
Call your veterinarian promptly if the metal chewing is new, repetitive, compulsive, or increasing. Also call if your cat has bad breath, red gums, drooling, pawing at the mouth, chewing on one side, dropping food, weight loss, appetite changes, vomiting, diarrhea, constipation, belly pain, hiding, lethargy, or any chance of swallowing metal.
Seek urgent care if your cat swallowed or may have swallowed a needle, pin, hook, staple, screw, coin, battery, magnet, jewelry clasp, ornament hook, wire, or any sharp or unknown object. Emergency signs include gagging, choking, repeated vomiting, collapse, severe pain, blood from the mouth or stool, a swollen belly, or inability to eat or drink.
What to do right now
Remove access to the metal object calmly. Do not pull string, wire, or a sharp item from your cat’s mouth or rear end if it seems stuck; contact a vet instead. If you can do so safely, save the object or a photo of it, including packaging or material details. This helps your vet judge size, shape, coating, toxicity risk, and whether imaging is needed.
Check the surrounding area for missing pieces. Look for blood, broken fragments, loose screws, chewed cords, or anything small enough to swallow. If the item could contain lead, zinc, copper, batteries, solder, fishing weights, paint, lubricant, or chemical residue, treat it as higher risk and ask your veterinarian or animal poison-control service for guidance.
How to stop the habit safely
Start with access control. Put away jewelry, paper clips, staples, sewing supplies, batteries, coins, twist ties, craft wire, holiday hooks, and small hardware. Cover or block metal furniture edges that your cat targets. If cords are part of the pattern, use the steps in this guide to stop cats from chewing cords, because electrical chewing adds shock and burn risks.
Offer safer outlets. Choose cat-safe chew toys, kicker toys, puzzle feeders, food-dispensing toys, scratching surfaces, climbing spaces, and daily interactive play. Rotate toys so they stay interesting. For kittens, ask your veterinarian which chew toys are appropriate for teething and which are too small, brittle, or easy to shred.
Make the environment easier to live in. Feed on a predictable schedule, provide multiple water stations, keep litter boxes clean, and give each cat quiet resting spots and vertical space. In multi-cat homes, reduce conflict by spreading food, water, litter boxes, scratchers, and beds across different areas.
Use deterrents carefully. Bitter sprays or covers may help with some objects, but they should not be used on anything your cat can ingest, and they are not a substitute for removing dangerous items. Avoid essential oils, harsh chemicals, hot pepper, or punishment. These can be unsafe, increase stress, or make the behavior harder to address.
What your vet may check
Your veterinarian may examine your cat’s mouth, teeth, gums, abdomen, weight, diet, and behavior history. Depending on the situation, they may recommend dental evaluation, blood work, fecal testing, imaging, parasite control review, diet changes, pain control, or a behavior plan. If the object was swallowed, imaging can help locate it and guide the safest next step.
The best plan depends on the cause. A bored cat needs enrichment. A stressed cat needs stress reduction and predictable resources. A cat with dental pain needs veterinary dental care. A cat with pica-like swallowing risk needs both medical workup and strict household safety changes.
Bottom line
Metal chewing can look quirky, but it can become a real health risk. Remove metal hazards, give your cat safer ways to chew and play, and involve your veterinarian if the behavior is repeated, sudden, intense, or connected to any signs of illness. If swallowing is possible, treat it as urgent until a veterinary professional tells you otherwise.
