Tendonectomy
A tendonectomy is a surgical alternative to the declawing (onychectomy) of cats. Instead of removing the claws, a tendonectomy removes part of the flexor tendons that are used to control them, preventing the cat from being able to extend its claws.
Because the claws are not removed, they continue to grow, and need to be clipped on a regular basis; if not, they can grow into the pads on the bottom of the cat's feet. A cat that has had a tendonectomy should not be allowed outdoors.
Reasons for Tendonectomy
A tendonectomy is usually performed to keep a cat from scratching and destroying furniture and other home furnishings, and/or from scratching people. It is often perceived as being less traumatic for a cat then declawing, which removes the claws by amputating all or part of the end bones of the toes. According to the American Veterinary Medical Association (AVMA), "Declawing of domestic cats should be considered only after attempts have been made to prevent the cat from using its claws destructively or when its clawing presents a zoonotic risk for its owner(s)." The AVMA takes the same position on tendonectomy.
Alternatives to Tendonectomy
Scratching is normal behavior for cats, who use it to mark territory, remove husks from their claws, and help them stretch. Tendonectomy is not, in most cases, medically necessary. Providing a cat with a scratching post, or applying temporary synthetic nail caps, are often good alternatives.
