Numerous procedures performed on domestic animals are usually more invasive than purely cosmetic alterations, but differ from types of veterinary surgery that are performed exclusively for health reasons. Such procedures have been grouped together under the technical term 'mutilatory' by the Royal College of Veterinary Surgeons in a report describing the reasons for their being conducted and their welfare consequences, [1] and by others. [2] [3]
The term mutilatory generally connotes some form of disfigurement or even maiming. There are multiple definitions and interpretations that carry varying degrees of emotional intensity. Merriam-Webster defines "mutilate" as "to cut up or alter radically so as to make imperfect", but gives a relatively mild example: "the child mutilated the book with his scissors". [4] Animal rights advocates often pejoratively refer to these procedures as mutilations. [5] [6] PETA states that one issue with current forms of non-human animal treatment is that the animals "are mutilated and confined to tiny cages so that we can kill them and eat them." [7]
The Royal College of Veterinary Surgeons noted that the term mutilation is often an emotive one, having implications in common usage of maiming and disfigurement. They stated that there was no satisfactory alternative term that would suffice for their purposes. Their definition is a narrower one: "covering all procedures, carried out with or without instruments which involve interference with the sensitive tissues or the bone structure of an animal, and are carried out for non-therapeutic reasons." [1]

Mutilation or maiming is severe damage to the body that has a subsequent harmful effect on an individual's quality of life.
Cattle mutilation is the killing and mutilation of cattle under supposedly unusual, usually bloodless circumstances. This phenomenon has been observed among wild animals as well. Worldwide, sheep, horses, goats, pigs, rabbits, cats, dogs, bison, moose, deer and elk have been reported mutilated with similar bloodless excisions; often an ear, eyeball, jaw flesh, tongue, lymph nodes, genitals and rectum are removed.
Docking is the removal of portions of an animal's tail. While docking and bobbing are more commonly used to refer to removal of the tail, the term cropping is used in reference to the ears. Tail docking occurs in one of two ways. The first involves constricting the blood supply to the tail with a rubber ligature for a few days until the tail falls off. The second involves the severance of the tail with surgical scissors or a scalpel. The length to which tails are docked varies by breed, and is often specified in the breed standard.
Myiasis, also known as flystrike or fly strike, is the parasitic infestation of the body of a live animal by fly larvae (maggots) that grow inside the host while feeding on its tissue. Although flies are most commonly attracted to open wounds and urine- or feces-soaked fur, some species can create an infestation even on unbroken skin and have been known to use moist soil and non-myiatic flies as vector agents for their parasitic larvae.
Mulesing is the removal of strips of wool-bearing skin from around the breech (buttocks) of a sheep to prevent the parasitic infection flystrike (myiasis). The wool around the buttocks can retain feces and urine, which attracts flies. The scar tissue that grows over the wound does not grow wool, so is less likely to attract the flies that cause flystrike. Mulesing is a common practice in Australia for this purpose, particularly on highly wrinkled Merino sheep. Mulesing is considered by some to be a skilled surgical task. Mulesing can only affect flystrike on the area cut out and has no effect on flystrike on any other part of the animal's body.
Onychectomy, popularly known as declawing, is an operation to remove an animal's claws surgically by means of the amputation of all or part of the distal phalanges, or end bones, of the animal's toes. Because the claw develops from germinal tissue within the third phalanx, amputation of the bone is necessary to fully remove the claw. The terms onychectomy and declawing imply mere claw removal, but a more appropriate description would be phalangectomy, excision of toe bone.
Lumpectomy is a surgical removal of a discrete portion or "lump" of breast tissue, usually in the treatment of a malignant tumor or breast cancer. It is considered a viable breast conservation therapy, as the amount of tissue removed is limited compared to a full-breast mastectomy, and thus may have physical and emotional advantages over more disfiguring treatment. Sometimes a lumpectomy may be used to either confirm or rule out that cancer has actually been detected. A lumpectomy is usually recommended to patients whose cancer has been detected early and who do not have enlarged tumors. Although a lumpectomy is used to allow for most of the breast to remain intact, the procedure may result in adverse affects that can include sensitivity and result in scar tissue, pain, and possible disfiguration of the breast if the lump taken out is significant. According to National Comprehensive Cancer Network guidelines, lumpectomy may be performed for ductal carcinoma in situ (DCIS), invasive ductal carcinoma, or other conditions.
Devocalization is a surgical procedure where tissue is removed from the vocal cords.
Mayhem is a common law criminal offense consisting of the intentional maiming of another person.
Pinioning is the act of surgically removing one pinion joint, the joint of a bird's wing farthest from the body, to prevent flight. Pinioning is often done to waterfowl and poultry. It is not typically done to companion bird species such as parrots. This practice is unnecessary and restricted in many countries.
Horse-ripping, or horse slashing, is an animal cruelty phenomenon involving serious injuries in horses, often involving mutilation of their genitalia and slashing of the flank or neck. It has not been established, however, how often these injuries are caused by human cruelty. "Horse-ripping" is not an entirely neutral term since it implies there is always a human act behind the mutilations.
Organ replacement in animals is an emerging field in veterinary science, focusing on improving and prolonging the lives of animals through the replacement or augmentation of damaged or dysfunctional organs. Despite its relative rarity compared to limb prosthesis, strides have been made over the decades, with notable milestones such as the first pacemaker surgery on a dog in 1968 and successful kidney transplants in cats since the mid-1980s. This field faces challenges, particularly in canine programs, due to issues related to immunosuppression. Ethical considerations also exist, particularly concerning the treatment of donor animals, underscoring the need for ongoing discussions and regulations in this dynamic field.
Veterinary surgery is surgery performed on non-human animals by veterinarians, whereby the procedures fall into three broad categories: orthopaedics, soft tissue surgery, and neurosurgery. Advanced surgical procedures such as joint replacement, fracture repair, stabilization of cranial cruciate ligament deficiency, oncologic (cancer) surgery, herniated disc treatment, complicated gastrointestinal or urogenital procedures, kidney transplant, skin grafts, complicated wound management, and minimally invasive procedures are performed by veterinary surgeons. Most general practice veterinarians perform routine surgeries such as neuters and minor mass excisions; some also perform additional procedures.
Docking is the intentional removal of part of an animal's tail or, sometimes, ears. The term cropping is more commonly used in reference to the cropping of ears, while docking more commonly—but not exclusively—refers to the tail; the term tailing is used, also. The term has its origins in the living flesh of the tail, commonly known as the dock, from which the animal's tail hairs grow.
Dehorning is the process of removing the horns of livestock. Cattle, sheep, and goats are sometimes dehorned for economic and safety reasons. Disbudding is a different process with similar results; it cauterizes and thus destroys horn buds before they have grown into horns. Disbudding is commonly performed early in an animal's life, as are other procedures such as docking and castration. In some cases, it can be unnecessary.
The National Animal Interest Alliance (NAIA) is a non-profit organization in the United States dedicated to promoting animal welfare and animal husbandry practices, strengthening the human-animal bond, and safeguarding the rights of responsible animal owners and professionals through research, public education and public policy. The NAIA mission is "to promote the welfare of animals."
Cropping is the removal of part or all of the external flaps of an animal's ear. The procedure sometimes involves bracing and taping the remainder of the ears to train them to point upright. Almost exclusively performed on dogs, it is an old practice that was once done for perceived health, practical or cosmetic reasons. Veterinary science states there is no medical or physical advantage to the animal from the procedure, leading to concerns of animal cruelty over performing unnecessary surgery on animals. In modern times, cropping is banned in many nations, but is still legal in a limited number of countries. Where permitted, it is seen only in certain breeds of dog, such as pit bull and bull terrier type breeds, the Doberman Pinscher, Schnauzer, Great Dane, Boxer and Cane Corso.
Dubbing is the procedure of removing the comb, wattles and sometimes earlobes of poultry. Removing the wattles is sometimes called "dewattling".
The Croydon Cat Killer is the name given to an individual alleged to have killed, dismembered and decapitated more than 400 cats and various other animals across England, beginning in 2014 in Croydon, South London. Reports of cat deaths attributed to the killer were spread across and around London, and as far north as Manchester. However, in 2018, the Metropolitan Police concluded that the mutilations had not been carried out by a human and were likely caused by wildlife predation or scavenging on cats killed in vehicle collisions, a conclusion subsequently supported by further research.
Nigeria has the highest rate of female genital mutilation (FGM) in the world in total numbers. It is usually experienced by girls aged 0 to 15 years old. It involves either partial or complete removal of the vulva or other injury to the female genital organs and has no medical benefit.
