I believe if cat owners really understood what occurs during a declawing surgery, they would never, ever choose to put their pet through this barbaric procedure.
Here’s what you must understand: while other mammals, including humans, walk on the soles of their feet, cats walk on their toes.
When you declaw your cat, you’re literally cutting off part of her toes.
Tragically, many people believe “declawing” only involves removing the claw. But because the claw grows out of bone, declawing requires amputation of the entire first joint of each of a cat’s toes. The surgery removes not only the claw, but bones, nerves, the joint capsule, collateral ligaments, and the flexor tendons.
Normally, kitties carry 60 percent of their body weight on their front feet ‐ more than half of their body weight! If her front paws become damaged, even temporarily, the effects are felt all the way through the cat’s wrist, elbow, and shoulder, down the spine to the tail.
With declawing, you change your cat's ability to walk naturally. She’s forced to shift her weight backwards, which can lead to collapse of her wrists. Declawed cats sometimes end up walking on their ankles or wrists, which is very painful.
Declawing also severs her tendons, causing them to contract and pull the toes back. This changes the angle at which the foot connects with the ground.

Here’s another problem with declawing… When a small piece of bone is purposely left in, a painful regrowth can occur, even as much as 15 years later. All in all, declawing can lead to a whole host of physical complications such as chronic small bone arthritis, degenerative joint disease, and neuralgia.
Yet, many cats, being the stoic creatures they are, often appear normal after a declawing procedure. They may go back to playing, climbing and jumping, but none of it is normal movement because their entire physiology has been altered.
And down the road, behavioral problems can arise.
The Emotional Consequences of Declawing Your Cat

Declawing offers no benefits for your cat – only risks
Pet owners are often caught off guard when behavioral changes arise after declawing. Most of the time their veterinarian hasn’t warned them it can ‐ and does ‐ happen.
I believe owners must be aware they are risking significant and permanent behavioral side effects, in addition to the many potential physical effects I already mentioned when they choose to declaw their pet.
Many cats experience emotional difficulties from declawing surgery. Owners report that their pet becomes morose, withdrawn, irritable, and even aggressive.
Imagine if every step you took caused you severe pain, you might act that way too!
Pet owners notice personality changes in their cat, too.
Recently declawed cats often become nervous, fearful and aggressive. Having lost their instinctive primary defense mechanism against predators, they resort to using their last remaining means of defense ‐ their teeth.
Many cats who were confident on the ground when they still had their claws, begin spending much of their time on elevated surfaces like the top of the refrigerator, countertops, or high shelving in closets once they’re declawed.
Some declawed kitties, once they discover they can no longer mark with their claws, begin to urinate around the house to mark their territory. This can result in long-term inappropriate elimination problems.
Tragically, declawing is still a routine procedure for many vets. No matter what they claim, a 2001 study published in a prominent veterinary journal reported that 80 percent of declawed cats had at least one medical complication following surgery and one-third developed behavior problems, such as biting or urinating outside their litter box.
Bottom line… there are no benefits to your pet from declawing ‐ only serious risks. I believe that finding alternatives to this barbaric surgery is the humane and loving thing to do for your cat.
