What are the potential complications of declawing?
Post-surgical complications: Abscesses and claw regrowth can occur a few weeks to many years after surgery. Chronic or intermittent lameness may develop. In one study that followed cats for only 5 months after surgery, nearly 1/3 of cats developed complications from both declaw and tendonectomy surgeries (digital tendonectomy is a procedure whereby the tendons that extend the toes are cut; it's sometimes promoted as an "alternative" to declawing. However, because these cats require constant maintenance and frequent nail clipping to prevent injury, most are eventually declawed anyway). Biting and urinating outside the litterbox are the most common behavior problems reported, occuring in over 30% of cats.
Pain: It is impossible to know how much chronic pain and suffering declawing causes, because cats are unable to express these in human terms. However, we can compare similar procedures in people. Nearly all human amputees report "phantom" sensations from the amputated part, ranging from merely strange to extremely painful (about 40% of such sensations are categorized as painful). Because declawing involves at least ten separate amputations, it is virtually certain that all declawed cats experience phantom pain in one or more toes. In humans, these sensations continue for life, even when the amputation took place in early childhood. There is no physiological reason that this would not be true for cats; their nervous systems are identical to ours. Cats are stoic creatures, and typically conceal pain or illness until it becomes overwhelming. With chronic pain, they simply learn to live and cope with it. Their behavior may appear "normal," but a lack of overt signs of pain does not mean that they are pain-free.
Joint Stiffness: In declawed (and tendonectomized) cats, the tendons that control the toe joints retract after surgery, and these joints become essentially "frozen." The toes remain fully contracted for the life of the cat. In cats who were declawed many years earlier, these joints often cannot be moved, even under deep anesthesia. The fact that most cats continue to make scratching motions after they are declawed is often said to "prove" that they do not "miss" their claws. However, this behavior is equally well--and more realistically--explained as desperate but ineffective efforts to stretch those stiff toes, legs, shoulders and backs.
Arthritis: Research has shown that, in the immediate post-operative period, newly declawed cats shift their body weight backward onto the large central pads of the feet, and off the sore toes. This effect was significant even when strong pain medication was given, and remained apparent for the duration of the study (up to 40 hours after the surgery). If this altered gait persists over time, it would cause stress on the leg joints and spine, and would lead to damage and arthritic changes in multiple joints. A recent study showed that arthritis of the elbow is very common in older cats. When contacted, the researchers admitted that they did not ask or record whether the cats were declawed, perhaps preferring the "don't ask, don't tell" policy so as not to anger those many veterinarians who make a lot of money from declawing.
Litterbox Problems: Experts say that declawed cats have more litterbox problems than clawed cats, and the statistics prove it. Not many people would choose urine-soaked carpeting (or floorboards, sofa cushions, walls, bedding, or mattresses) over a few scratch marks, but this is a distressingly common outcome. In one survey, 95% of calls about declawed cats related to litterbox problems, while only 46% of clawed cats had such problems - and most of those were older cats, many of them with physical ailments that accounted for the behavior. Some households with declawed cats have spent thousands of dollars replacing drywall, carpets, and subfloors to repair urine damage.
Biting: Some experts believe that cats who are declawed are likely to become biters. Many declawed cats do seem to "notice" that their claws are missing, and turn to biting as a primary means of defense--not a good choice for a cat in a home with children or immunocompromised individuals.
Change in Personality: This is a common complaint: "my cat has never been the same." A friendly, delightful kitten may become a morose, fearful, or reclusive cat, never to recover its natural joy, grace, and love of exploration.
Neglect, Abandonment, and Abuse: Declawing that results in biting or inappropriate elimination outside the litterbox may result in the cat being permanently locked in the basement, dumped at a shelter, or simply abandoned. Many cats are exiled to a life outdoors because of these unwanted behaviors. There, they also risk injury or death by dogs, cars, wild predators, disease, poison, and other hazards of outdoor life; even more so than clawed cats who retain their primary defenses. People who work with feral cat Trap-Neuter-Release programs often find declawed cats in their traps--cats who should never have been outside at all. These cats once had homes, but were abandoned in an alley or field--almost certainly due to behavior problems resulting from declaw surgery. The claim by veterinarians that "declawing keeps cats in their homes" clearly isn't true for these declawed cats who lost their homes and were abandoned to an uncertain fate. There is no way to know how many cats are dumped this way, but based on experiences in Denver, a typical urban environment, the number is likely in the many thousands.
Death: There is always a small but real risk of death from any general anesthesia, as well as from bleeding or other surgical complications. If a declawed cat that develops a behavior problem is taken to a shelter, such behavior makes him unadoptable, and he will promptly be euthanized (killed). For exiled cats, it is unfortunately common for outdoor cats to be stolen and used as defenseless live bait to be torn apart by fighting dogs, or sold to laboratories or biological suppliers. It's an ugly reality that a tame, friendly, declawed cat makes an ideal experimental subject.
