What is declawing in cats
Declawing is the surgical amputation of toe bones, not just claws, and carries significant risks of chronic pain, behavioral changes, and long-term health complications.
Declawing is the surgical amputation of the last bone of each toe, not merely the removal of the claw itself. The procedure, technically known as onychectomy, removes the distal phalanx to eliminate the claw, a fact that makes it a form of amputation rather than a simple grooming treatment.
It is an amputation, not a trimming
The claw grows from germinal tissue located inside the third phalanx, the end bone of the toe. To fully remove the claw, the surgeon must amputate this bone. While the terms onychectomy and declawing imply a simple nail removal, the procedure is more accurately described as a phalangectomy. This distinction matters because the cat is left without a digit, altering the mechanics of the entire paw.
Methods vary but risks remain
There are three primary surgical methods: scalpel blade, guillotine trimmers, and laser. Despite the prevalence of these techniques in North America, no standard practice exists regarding the tools used, the administration of pain relief, or the optimal age for the surgery. Crucially, no technique has been proven to eliminate the complications associated with the procedure. The International Society of Feline Medicine states that even with improved techniques, the procedure is considered unethical unless required to manage a medical condition.
Recovery involves significant pain and complications
As an orthopedic surgery requiring general anesthesia, the procedure demands multi-modal pain management before, during, and after the operation. A 2018 study found that inappropriate surgical technique was common, with retained bone fragments further increasing the risk of back pain and adverse behaviors. Recovery time typically ranges from three days to two weeks, but medical complications are frequent. At one veterinary teaching hospital, between 50 and 80% of cats experienced one or more medical complications post-surgery. Reported issues include hemorrhage, infection, abscess, tissue necrosis, chronic pain syndrome, and in severe cases, the protrusion of the second phalanx or claw regrowth years later.
Behavioral changes are common and lasting
Declawed cats face a significantly higher risk of developing unwanted behaviors compared to non-declawed cats. A study of 274 cats found that inappropriate toileting, biting, aggression, and overgrooming occurred roughly seven, four, and three times more often, respectively, in declawed cats. These cats were also almost three times more likely to be diagnosed with back pain, likely due to altered gait and compensatory weight shifting. While some owners report satisfaction, other studies indicate that 16% of declawed cats develop new behavior problems, and they are more likely to be referred to veterinary teaching hospitals for behavioral issues. The data suggests that while the surgery may prevent scratching, it often replaces one problem with others, including increased aggression and litter box avoidance.
Legal status varies globally
The practice is banned in at least 38 countries, including most of Europe, New Zealand, Japan, and Turkey, where it is considered an act of animal cruelty. In the United Kingdom, the Animal Welfare Act 2006 explicitly prohibits interference with bone structure unless for medical treatment. In North America, the practice remains controversial and is increasingly restricted. While it was once performed on approximately 25% of domestic cats, major veterinary clinic chains announced in 2020 that they would no longer offer elective declawing. In Canada, the practice is banned in most provinces, with Ontario being the sole exception where it remains legally permitted, though the Canadian Veterinary Medical Association strongly opposes it.
Medical indications are rare
While elective declawing is often performed for convenience, the procedure is medically indicated only in specific cases. These include comminuted fractures, pseudarthrosis, intraarticular fractures, irreparable luxation, neoplasia, and chronic infections that cannot be managed otherwise. For the vast majority of cats, the surgery is not a medical necessity but a choice made to protect household possessions or prevent scratching of people, a practice that carries substantial physical and psychological risks for the animal.
