How do I trim my cat's claws?

Claws are a cat's tools for gripping, climbing, balancing, hunting, kneading and defence. The front claws are retractable: at rest they are sheathed in skin and fur, which keeps them sharp.

Scratching is a normal, inborn need, not bad behaviour. It strips the worn outer sheath off the claw so a sharp new one shows underneath, stretches and exercises the body, and marks territory with scent from glands in the paws. Because the need is inborn it cannot be trained away. It can be guided to surfaces you choose, which is what scratching posts are for.

A curved, claw-shaped shell found near a scratching post or on a blanket is just a shed sheath. It does not mean the cat lost a claw. Scratching can rise when a cat is stressed or when cats in one home are in conflict, so a sudden change in scratching is worth noticing.

Trimming never replaces scratching. A cat with trimmed claws still needs places to scratch. Studies on scratching are limited and much of the advice here is expert opinion, so ask your vet what suits your cat.

Not every cat does. If your cat's claws have never become overgrown, scratching and activity are keeping them in shape, and regular checks may be enough. Outdoor and very active cats wear their claws down by climbing and scratching and usually need little or no trimming. They use their claws to climb and escape, so cutting them short can hold them back until the claw is sharp again.

Indoor cats often keep a good length on posts and scratching blocks, but may still need trimming from time to time. Indoor and older cats are the ones most at risk of long claws. Older cats, and cats with arthritis, extra weight, nerve problems or limited movement, wear their claws less and often need regular help.

Trim because claws are too long, not because they feel sharp. Reasons to trim: long claws snag and break, can curl into the pad, and scratch people and furniture more. Trimming lowers the damage but is only a partial fix, because the urge to scratch stays. A trim is not declawing. Trimming takes off a small amount of the dead keratin at the tip and leaves bone, tendons and joints untouched.

There is no single interval. It depends on the cat's age, how active it is, how much it scratches and what surfaces it has. Look at the paws every two to four weeks and trim when the claws need it, not because a number of days has passed. Sources that give a rhythm for cats that do need trimming range from about every 10 to 14 days to every 2 to 4 weeks, about monthly, or about every 6 to 8 weeks. That spread is why a regular look matters more than a fixed date.

Older cats, cats with extra toes and cats that move less may need a weekly look. The front claws stay sharper and often need trimming more often than the back claws, which wear down when the cat walks. Dew claws are the exception and need checking each time. After a trim a cat may want to sharpen its claws again and scratch more, sometimes in new places. Have posts ready.

Signs are a clicking or tapping sound on hard floors; claws that stay visible while the cat is resting, or that curl towards the pad (one guide says a curve past about a quarter circle is a sign to trim); claws that catch on carpet, blankets or furniture, or a paw pulled away after a snag; and a cat that struggles to retract its claws, or paws at its feet, because long claws are painful.

A claw that has curled into the pad, or a toe that is red, swollen or bleeding, needs a vet, not a trim at home.

Sharp clippers made for cats. Scissor-style and guillotine-style cat clippers are both used. Blunt blades crush or split the claw, so replace them when they stop cutting cleanly.

Human nail clippers and scissors are the most debated tool. Their flat blades can squash a thick cat claw and split it, and most guides advise cat clippers. A few vet practices accept clean, sharp small human clippers for fine tips. Never use nail scissors.

A nail grinder is an alternative that files the claw down to a rounder edge, but it is louder than clippers. Some cats dislike the noise or the feel, so try it only after the cat is calm with paw handling. A file can smooth the edge after cutting.

Keep a pet styptic powder within reach in case a claw bleeds. Cornflour (cornstarch) or flour is the usual stopgap. Also have clean gauze, a bright light, a non-slip towel or mat, treats and, if the cat accepts it, a helper.

Step 1. Get your cat used to it first. For some days touch and hold the paws, press a toe gently, show the clippers and let the cat sniff them, and give a treat each time. Do this when you are not trimming.

Step 2. Pick a calm moment: the cat is sleepy, or has just eaten, played or woken up, in a quiet, well-lit room with other pets away and doors and windows shut. Do not start when the cat is alert, tense or upset.

Step 3. Hold the cat in your lap, either facing away from you or towards you, or have a helper hold it. Use as little restraint as possible. Holding the elbow or ankle gives more control than holding the paw itself.

Step 4. Put a finger under the toe pad and your thumb on top, and press gently so the claw comes out. Never pull or squeeze the toe.

Step 5. Find the pink quick if the claw is light. Cut only the clear, sharp tip, just before the claw begins to curve, in one clean cut from top to bottom and not side to side. Cutting at an angle that removes the hook is the aim.

Step 6. Do one or two claws, then reward, and stop. The whole cat does not have to be done in one sitting. Spread it over days if needed. One calm claw is better than a fight.

Step 7. Stop at once if the cat pulls away again and again, flattens its ears, lashes its tail, growls, pants or tries to bite. Try again another day.

Step 8. Check the cut end is dry, without cracks or pink tissue, smooth it with a file if it is rough, then give the reward. Learn first: ask a vet or a nurse to show you the hold and how much to take off, before you try alone.

The quick is the pink, triangular living tissue at the base of the claw. It holds blood vessels and nerves, so cutting into it hurts and bleeds. Cutting only the tip does not hurt.

In a light claw the quick shows as pink. Cut the clear tip beyond it and keep a clear margin. Sources suggest a couple of millimetres or a little more, so when in doubt, cut less.

In a dark claw you cannot see the quick. Shine a bright light from above or below, or look from the side, and cut in several small pieces. If the edge of the quick is still unclear, take off only the narrow hooked tip and trim more often, or let a vet show you. If the cat is very wriggly, has black claws, or has claws growing into the skin, one vet practice advises asking a vet to do it.

Most cats have 18 claws: five on each front paw, the first of them the dew claw, and four on each back paw.

The dew claw sits high on the inside of the front leg and does not touch the ground. It hardly wears down, can grow long even when the other claws are fine, and can curl into the skin. Check it every time and trim it when needed. Scissor-style clippers are often easier for it.

Healthy back claws need no routine trimming. Trim them only if they are long, damaged or catch on things, and then take only the needle-like tip. Cats with extra toes (polydactyl cats) have claws that may never touch a scratcher and can grow in odd directions or between toes, so look at each one.

No source gives a minimum age. What they do say is to start early with handling: touch the paws, show the clippers and reward, so the cat is at ease long before it needs a trim.

Trim a kitten's claws only when they need it, and keep each session very short with treats. Raise it at the first vet visit. Vets can show you how and are advised to give scratching and training advice from the first visit. Clicker training can help with paw handling.

With age, claws can get thicker, longer, more curved and brittle, and an older cat scratches and grooms less. Overgrown claws can curl into the pad, causing pain, infection and limping, and they can snag on carpet.

A claw that has already grown into the pad should not be pulled or cut out at home. It needs a vet. Thickened, discoloured, swollen or oozing claws can point to an illness and should be looked at by a vet, not trimmed again and again.

With arthritis or pain, ask the vet. Treating the pain may help the cat feel more comfortable and move more, and a vet or nurse can trim safely in short, gentle visits.

Stay calm and release any pressure on the toe. A frightened cat that pulls away can make it worse. Press clean gauze or cotton wool firmly on the claw tip for a few minutes, without lifting it again and again to look.

Pet styptic powder on the tip, used as its label says, is the usual help. Without it, dabbing the tip in cornflour (cornstarch), flour or a dry bar of soap is the common stopgap. Keep the cat calm and indoors until the bleeding has stopped, then watch the toe over the next days for pain, redness, swelling or discharge.

Call the vet if it still bleeds after about 10 minutes of steady pressure (sources say anything from 5 to 15 minutes), if it bleeds heavily or starts again, if the cat has a clotting problem or takes medicine that affects clotting, or if the toe becomes swollen, red or sore. A broken or torn claw is very painful. The cat may limp, hold the paw up or whine. A vet usually needs to remove the damaged part, because the nail bed is attached to bone and infection can be serious. Do not pull it off.

After a quick cut, make the next sessions short, with treats and very careful cutting, because the pain can make the cat wary.

Stop. Never force a cat or punish it. Several short, calm sessions are better than one bad one. Build up in small steps: a treat while you touch the shoulder, then the paw, then hold a paw briefly, then press one toe, then show the clippers without cutting, then cut one claw while the cat eats. Move on only when the cat stays relaxed at the current step.

A snug towel wrap with one leg out, and a helper, can calm some cats. Never squeeze or pin a cat down. A vet clinic or a groomer can trim the claws, and many clinics will also show you how. Some clinics offer nail trims at a lower price or free of charge.

For a cat that is very afraid, aggressive or in pain, a vet can make an anxiety plan. Sedation is only on the vet's instruction. Never give human or unprescribed sedatives.

Posts help a cat shed its outer sheaths and keep claws in shape, but they do not replace trimming for older cats, cats with limited movement, or dew claws. A good post is stable, tall enough for a full stretch (about 60 to 90 cm or more, taller than the stretched cat), and can be vertical or horizontal. Most cats prefer sisal rope, with carpet, wood and corrugated cardboard also popular. Older cats may lean a little to carpet.

Put posts where the cat already scratches, next to where it sleeps (cats often scratch after waking), near windows and in more than one room. With several cats, offer several posts. Reward use with treats or praise. Catnip or a toy dangled on the post can help, though catnip does not work on most kittens under four months. Do not take the paw and drag it down the post.

To make a favourite spot less attractive while the cat learns, put the post in front of it and cover the spot with double-sided tape, a tight sheet or plastic. Foil and upside-down carpet runners only move the scratching somewhere else. Do not throw away a worn post, because cats like shredded, familiar ones.

Play, a healthy weight and a calm home keep claws in use and can lower stress-related scratching. Synthetic pheromone sprays have only weak evidence, and some studies were run by the makers. If a cat suddenly scratches far more or damages things, ask the vet to rule out pain and stress. A behaviourist can help.

Soft caps are glued over the claws. They blunt the claw to protect furniture, people or other animals, and the cat can still extend its claws. They are usually replaced every four to six weeks, as the claw sheds, though other sources say monthly or every 6 to 12 weeks.

Vets say they suit some cats but not all. They need a cat that accepts its paws being handled, and some cats resent them and pull them off quickly. A clinic can fit them, or you can learn to. Caps must be fitted properly, the glue must not be overdone, and the cat should be watched to check it still sheds old claws naturally. A cap does not stop growth, so claws still need checking. They are seen as a good temporary help while a cat learns to use a post.

Not everyone agrees: one cat charity advises against caps because they may stop retracting and scratching and can cause stress. Ask your vet whether they would suit your cat.

Declawing (onychectomy) is surgery that amputates the last bone of each toe, the one the claw grows from, together with the claw. It is not the removal of a nail. It is usually done on the front paws. Trimming removes only a small amount of dead keratin from the tip. Declawing is an amputation, and trimming is not a milder form of it.

Cutting the tendon so the claws cannot extend (tendonectomy) is not recommended either: the nails overgrow and still need constant trimming, and some cats have lasting discomfort. Declawing does not stop the urge to scratch. It only prevents the damage.

Removing a toe bone for medical reasons, such as a nail-bed tumour, severe injury or infection, is a different matter and can be needed.

Vet and animal welfare bodies strongly oppose elective declawing. One cat welfare charity calls it mutilation unless there is a genuine medical reason, and a Canadian vet regulator calls it ethically unacceptable. Risks include pain, bleeding, swelling, infection, nerve damage and the risk of anaesthetic. The risk of surgery rises with age.

Longer-term problems reported include lameness, tendon problems, bone fragments left behind that regrow or hurt, a changed way of walking, back pain, chronic nerve pain, and behaviour change such as using the litter box less, biting and over-grooming. In a study of 137 declawed and 137 non-declawed cats, declawed cats were more likely to have back pain, toilet problems, biting and over-grooming. Bone fragments were seen on X-ray in 63% of the declawed cats.

A declawed cat has lost a main way to defend itself and should be kept indoors or in a secure enclosure. Declawing does not prevent cat scratch disease, and health authorities do not recommend it for that. Most scratches do not cause the disease, which is usually spread by fleas, and washing a scratch with soap and water is the sensible step. It is not a cure for behaviour problems and should not be used as one. Data do not show that scratching cats are more likely to be given up, and a Canadian study found no rise in surrenders after a ban.

Declawing is banned or heavily restricted in a growing number of countries, states and cities, and the laws differ, so check the rule where you live. What applies in your country is further down, under 'What applies where you live'. If someone suggests it, ask your vet about the pain, the complications and the alternatives first. Vets are expected to offer non-surgical alternatives and a behaviourist. If your cat was declawed before you had it, tell the vet. Declawed cats should be checked at every visit for lameness, odd toe posture and pain. Signs can be shaking a limb, hiding or avoiding the litter box.
