There seems to be an alarming trend to have cats declawed...whether it's due to personal convenience, apartment house rules and regulations, or simple lack of knowledge on the part of responsible pet owners.
There are many fine vets out there that actively discourage declawing, but there are also many who perform this surgery on a regular basis while never completely informing the pet owner what this really entails nor explaining the possible dangers of the procedure. If people were more informed, perhaps this trend would reverse itself.
Declawing a cat is a major surgical procedure, performed under general anesthesia. It is actually amputation of the last joint on each toe, not a simple removal of the claw itself as many are led to believe. The following article explains the procedure of declawing.
Cats walk on their toes, unlike most mammals who walk on the soles of their feet. Their musculature, joints, tendons and ligaments are all designed to distribute their body weight to their toes.
The claw is not a nail like human fingernails or toenails. It is actually a part of the last bone in a cat's toe. If you were to "declaw" a human in the same way a cat is declawed, you would be amputating all 10 fingers at the last joint!
I found this description of the surgery in a veterinary textbook: "The claw is extended by pushing up under the footpad or by grasping it with Allis tissue forceps. A scalpel blade is used to sharply dissect between the second and third phalanx over the top of the ungual crest . The distal interphalangeal joint is disarticulated (disjointed), and the deep digital flexor tendon is incised (severed). The digital footpad is not incised.
