the best methods for trimming cat nails and recognizing when it is necessary for your pet's health

1. Introduction

For many cat owners, trimming their feline's claws is the last thing on the to-do list. That may be because trimming nails can take time and patience, both of which can be in short supply. But neglecting claws can lead to serious health problems, for kitties. Cats' claws are designed to elongate and to wear down as they scratch. Indoor cats need help with their manicures, as do senior cats, declawed cats, or kitties who, for some other reason, are not properly wearing down their nails. Helping cats with regular nail trims keeps cat claws shorter and safer.

Cat claws are made of keratin, the same material human fingernails and hair are made of. Like other parts of the body, nails are living tissues that grow and change over time. Cat claws grow in layers, with the core being soft and pink. A young cat claw is fully formed when it reaches maturity, taking about six months to develop a keratinized outer layer, which is the part of the claw that pet parents see. The outer layer is similar to a natural cat claw protector that can crack or wear out in some cases. It protects the inner core from injury and infections, which may occur when the inner core is exposed. If left untrimmed, the outer layer may build up, curling in and becoming ingrown.

If not trimmed regularly, claws will keep growing and may become dangerous and painful for the cat. They may hit the pads and grow into the wounds, which can become infected. They may also catch on carpet and fabrics, leading to tears to the claw and the cat getting stuck. Excessive claws may become a problem for a cat’s pet parent too, leading to scratches on legs and furniture. Young kittens, adults, and elder cats need regular nail trimming. Kittens and young cats should have paws handled, claws trimmed, and rewarded after. After they feel comfortable with #1 and #2, use cat claw clippers or cat nail scissors to trim the sharp tip off to keep the claws short. Adult cats need trimming after six to eight weeks.

1.1. Importance of Regular Nail Trimming

Cat nails, by nature, are sharp and the length of those nails may become a true nuisance over time. Two main considerations are mandatory: how to trim them and how to know when to trim has to be taken into account. Ultimately, a cat’s nails are a cat owner’s responsibility. Not only this responsibility, but also a foremost concern for pet health is too.

Many cats are outdoor cats. Climbing trees or hunting rodents outdoors are natural activities for outdoor cats. This is how nails are trimmed naturally. However, indoor house cats and apartment dwellers do not need their claws trimmed, often becoming long and dangerous to property and overall household.

Cats are reluctant to having their nails trimmed. Spaying of cats is usually easy to do, they just go to sleep and after waking up it’s done. However, for most cats, muzzle and restraint is needed to perform nail trimming. Their claws retract by default (in nature) but when nervous they come out and get extra sharp, making trimming much harder. Contrarily, some cats love nail trimming and ask for it every now and then.

Small and pointy nail clippers, models similar to those used for humans, are the best way to trim nails. Scissors are not appropriate to use, and generic looking clippers are able to break nails or make an uneven cut, which might hurt a cat and compel them not to allow nail trimming anymore. Cats hate as much as lawn mowers loud noises.

To make a task easy to accomplish with less effort is to hold a cat in a specific way, best done with two people. While one person is holding a cat belly up and tightly, the other one extends one leg with a towel. The towel has to cover the pads so they do not slip off the clippers. Only one claw should be trimmed at a time.

When claws are cut, the cat begins to act afraid (not in shock, it will want to run but can’t). However, with patience, it will become familiar with it. After a number of attempts, simply by holding the cat and pulling one paw, it will understand it will not injure it, getting used to having claws cut. Of course, if the nail blade gets inside the paw, it’s worth a discussion to stop doing it.

2. Understanding Cat Nail Anatomy

Many cat owners overlook the importance of their pets' claws. That's a shame because claws are vital to cats and, with some knowledge, their care is simple enough. Claws grow from the phalanges, the first bones of each digit. As they grow, the external part becomes keratinized, and a claw takes form. This keratinization has a dual purpose. On the one hand, it allows the cat to dig and latch onto prey. On the other hand, it shields delicate tissues such as the bone and the vascular system from the outside world. Claw keratinization keeps these tissues in optimal condition and influences their growth. Healthy claws grow constantly; if misused, they can grow too long.

Understanding the anatomy of animal claws is essential in diagnosing and preventing a variety of disorders. Mechanoreceptors provide vital information regarding forces acting on the claw, and grasping and digging forces alter claw shape. Longitudinal flesh stress analysis plays a major role in the ultimate claw shape and all functional aspects of the animal. Cats' claws have played increasing interest in the claw functionality and its effects on the adaptability of different habitats since the 1800s.

As cats' claws grow, the inner U-shaped, semi-translucent part becomes exposed. This part is delicately varnished and protected through grooming or use. It is splayed perpendicular to the digit axis; hence, nail damage can be avoided while quickly applying force to the joint. It also increases adhesion to prey and anchoring to the ground while running. This part has been observed in domesticated and wild felines. Cats do not retract their claws as commonly believed. Conversely, claws are kept outside the foot to prevent damage. When inactive, the claw's distal is tipped to the foot side, resulting in a desired, retracted appearance. The mechanisms regulating flexor tendons remain open for further study.

2.1. Structure of Cat Claws

Cats are unique in their anatomy. One of the most fascinating features about them is their claws. The curl of a cat's claw helps them climb trees and grip surfaces better. Much like human fingernails, cat claws are made of keratin. Human fingernails grow with a gradual and continually increasing pace. However, cat claws grow and become blunt, which will not let them grip surfaces. To protect the outer surface of the claw, newer and sharper claws are grown underneath. Eventually, the outer claw splits away from the surface and the process continues.

Claws have three layers. The outermost "hard" layer, the external sheath, is a thick and homogeneous keratin structure. The central "middle" layer, the corium, is a highly vascularized and innervated dermal layer. The inner "soft" layer, the ventral pad, is a thinned, non-smooth keratinized epithelium. The conditioning of cat claws plays a major role in determining the mechanical properties of the claw. Claws of wild-type cats are highly keratinized and have stiffer claws, while trichomoid cats have soft and flexible claws.

The thickness of the external sheath has been shown to correlate with the mechanical behavior of claws. The complex interactive biomechanical defenses against wear in claw evolution include curving claws, sharpening/peeling/honing, and conditioning of claws. They have developed remarkably specialized structures and material properties to serve as weapons and tools for capturing prey. These structures include the complicated dentition and claws. These specialized structures with exaggerated size and shape have been shown to further its evolutionary ecological fitness.

3. Methods for Trimming Cat Nails

Many pet owners may be unsure of the most effective ways to trim their cat's nails. Fortunately, there are several methods that they can adopt to assist them in keeping the trimming process smooth and quick. These methods include both specialized tools and training techniques. Some cats may adjust more easily to one method than another, and pet owners should also consider which method would be most comfortable for themselves.

Clippers specifically designed for cats are available at most pet stores, and these tools may be the best choice for most owners. Unlike human nail clippers, cat nail clippers are scissor-style clippers, which allow owners to slide the claw into the cuff of the tool and exert pressure on both handles, swiftly slicing through the claw. Many clippers also have a safety stop piece to help prevent too much of the claw from being clipped, which is especially useful for novice owners. Other types of clippers are designed like scissors that have a small cavity at the end of the blade that holds the claw as it is squeezed, with the scissor end cutting through the claw. Both types of trimmers are generally well-regarded, but the first type is more commonly used. Specialized nail clippers for kittens are available for smaller claws. For cats resistant to clippers, there are also electric cat nail trimmers that file down the claw rather than cut it. This type may reduce the severity of the claws' edge, making it less likely to snag, but many cats recoil violently from the sound of electric trimmers. If a cat refuses to use any type of clippers or trimmers, one final option is taking the pet to a veterinarian or grooming salon where either a technician or a vet will utilize trimmers and clippers to effect a proper nail trim.

To make the trimming run more smoothly, cats can be trained to accept their nails being cut. Shedding claws is a natural process, and many cats will try to file their claws down through scratching, but since most domesticated cats do not have access to a tree trunk, many of their claws will become uncomfortably long over time. To help facilitate such training efforts, it is advised that kittens be introduced to nail trimming at a young age if at all possible. Even if a kitten was born to a feral or free-roaming cat, taking the kitten in at a young age allows the pet to acclimate to the household and owners, and fitting in is much easier without long claws snagging on the environment. If adopting a full-grown cat, attempts can still be made to acclimatize the pet to the household environment and trimming claws, but the process may take longer as it is already set in its ways and assumptions about the environment. This does not mean prior cats will not be capable of picking up positive habits, as they will do so if it is rewarded.

3.1. Clippers vs. Scissors

Once the decision has been made to clip a cat's nails, the next consideration is whether to use clippers or scissors. Cat nail clippers generally come in one of two styles: "guillotine" or "scissors". Both styles are designed to cut the nail straight across, but there are some differences in how to use them.

Most professionals use either scissor-style or guillotine clippers specifically made for cats. Guillotine clippers have a hole in which to insert the nail; a cutting blade slides across the hole to "cut" the nail. Scissor-style clippers are held open like scissors with the nail held in a notch against a fixed blade. Either type works well, but many people choose one style or the other based on how effective or comfortable it feels when applying pressure to the clipper handle.

It's noteworthy to mention that human nail clippers, while small enough to use on a cat, aren't designed to cut the cat nail straight across - they cut the edge of the nail and may require much more pressure than intended, crushing the nail and injuring the quick. It is crucial to note that dog clippers are equally unsuited for cats - they are designed to cut much larger, thicker nails. Cat clippers are smaller and sharper, providing a clean cut with less effort.

On the other hand, scissors are straight or curved blades that simply cut across the nail. Some are designed to be used at a 45° angle (like human hair scissors), while others are straight and require holding the cat in one position while using a scissor motion to clip away from the body. Curved scissors tension the nail in the opposing position and are best used with a stable footing for the cat and some experience. It is usually easier to take off a large chunk of nail and a less tricky situation if the first cut is a little past the sharp tip of the claw.

4. Signs It's Time to Trim Your Cat's Nails

Keeping healthy claws is an important aspect of cat grooming that needs to be recognized, but often is not, until there are potentially painful side effects. Cat claws are not like dog claws, which grow blunt with activity. Unmaintained cat nails can grow in a spiral shape, curling under the toe and digging into pads, causing both pain and infection. Recognizing signs that claws need to be trimmed can save both the cat and the owner much distress.

Generally, indoor cats need claws trimmed about every three to four weeks, although some cats might require more or less frequent trimming, depending on how quickly their claws grow, the amount of activity/exercise they receive, and their scratching habits. Claws can be checked visually and by touch. Growth of the nail should be evident if it extends past the fleshy quick. If the cat is being poked while walking or if it needs to adjust its walk to avoid painful contact, it is time for a trim.

Other indications for a claw check include: Blood or injury from the claws snagging on fabric, furniture, or other materials. Scratching behavior has become destructive, leading to shredded carpets, upholstery, or other items. The cat has been punishing itself or more aggressive than usual in cleaning its feet, licking the paw pads raw. The pads or fur between the toes have begun to mat with dirt or debris.

Coat care supplies such as brushes and combs cannot answer the question of whether a trim is needed, but they can help to prevent some of the issues outlined above. Regular brushing of the coat removes loose furs and flakes, which will not only cut down on allergens and hairballs but also allow for a more thorough inspection of the paws.

4.1. Behavioral Indicators

A crucial aspect of feline health and welfare lies with their nails. In the wild, they maintain their nails' proper lengths by climbing and traversing rocky surfaces. As pets, environmental factors may require humans to intervene for their health and well-being. Certain physical and behavioral indications may suggest the need to trim the nails.

The most prominent behavioral indication that a cat needs its nails trimmed is its use of cat trees and scratching surfaces. When trimming is overdue, cats may begin repeating excessive motions involving their trees and furniture. Observing this behavior may indicate they are trying to compensate for the frictional surfaces not provided by natural settings. They may also collect more hairballs than normal due to their dragging motions.

Anecdotal evidence suggests that most cats react differently to properly maintained nails vs. untrimmed nails. A cat with recently trimmed nails would usually have less vigor when playing, and the intensity and excitement of their chasing motions would increase. On the contrary, a cat with overgrown nails digs and claws more aggressively.

Another behavioral indicator is the compulsive digging and shadow chasing of their paws. Over a certain length, nails can prevent cats from properly kneading their paws and digging soft surfaces. These compulsive motions generated by stress might also indicate unmet feline needs, such as hunting or proactive motions.

If no behavioral indication is observed, physical examinations can be employed. Cats may have difficulty grooming themselves, which could lead to matted fur, especially around the areas behind their ears and on their elbows. Scrapes, scratches, or even torn off skin can be a clear sign of untrimmed nails.

5. Health Benefits of Regular Nail Trimming

For domesticated cats maintained in an indoor environment or in multi-cat households, regular nail trimming is critical due to the lack of terrain where cats can naturally wear down their nails. Long and sharp claws are prone to snagging on carpeting, fastening onto upholstery, carpets, and clothing, and pulling out hair while climbing. Consequently, the cat may become frantic or behaviorally stressed in trying to extricate itself, causing damage to itself and the material. Nevertheless, some behavioral and structural anatomical precautions can prevent and control this problem. Nevertheless, nail trimming may become necessary in some cases.

Long claws can prevent cats from effectively gripping and holding on when jumping onto perches or climbing tall areas. Climbers may find themselves hanging or falling, causing harm or injury. Moreover, growing nails may curl and pierce the pads of the foot, resulting in susceptibility to infections. This often occurs in aged domestic cats because they do not scratch or shed their nails sufficiently, possibly due to underlying diseases such as arthritis or dental problems. Cranial cruciate ligament (CCL) injuries can also bring about numbness and inactivity. Long claws increase the risk of such consequences.

Another reason to trim nails is to prevent accidental injury to people. While cats normally retract their claws when they knead or walk, the claws may inadvertently scratch a companion. A sudden jolt or misstep can lead to a potentially deep injury. For homes with seniors and children, trimming becomes imperative. Nevertheless, regular claw trimming may be a more suitable alternative than declawing, as the latter is irrevocable and can alter a cat’s natural behavior.
