Voted no, probably surprises no one.
Here's my essay on declawing. It was a PM originally, I hope the recipient doesn't mind me reposting a slightly edited version here. Hey! if you read this
thanks for your decision and the intact toes of your cats!
Basically one of the worst problems that can happen with declawing is that any amputation and yes declawing is an amputation (multiple ones) is a very painful prodecure. Since cats use litterboxes it can happen that they associate the pain in their feet with the litterbox and refuse to use it. Also scratching in the litter with declawed feet is more uncomfortable than scratching with the claws. Try scratching in gravel with the knucles of your hands vs. normally with your finger tips and nails, it makes a big difference.
It happens not nearly all the time but it can and does happen and a cat that pees on beds and floors and sofas is a lot worse for any house than a cat with full claws. The cats that have developed that side effect are some of the ones that end up living out their lives in a shelter because no one wants to adopt a cat that pees and poos everywhere.
Then there's the danger of arthritis when they get old since a declawed cat spends their entire life walking in a slightly unnatural way. Their toes have been surgically altered so their balance and gait changes and this puts extra strain on their bones and ligaments which can start showing more when they get older. In addition to that some end up with a botched prodecure and the claw bed isn't removed completely and the claw grows back in inside the paw. So they'll need yet another operation.
Some have personality changes and regress a bit age wise from the trauma and become more clingy and less independent while others become aloof and stop playing as much.
My hunch is that those cats are dealing with phantom pain from the nerves that aren't there anymore.
Then some either usually fearful submissive ones or dominant alpha cats will start biting when they realise their claws aren't there. I.e their first line of defense is gone so they go straight for the bite. Others become more insecure so they overcompensate and get aggressive quickly, i.e with the "an attack is the best defence" way of thinking.
Trimming the claws is really helpful. That makes a *huge* difference when it comes to being scratched. It changes Nikita's claws from razors to well, very blunted razors. So she can run over my foot while playing and I just get a white mark in the skin that fades quickly and the skin isn't broken.
Anyway I know the declaw surgery doesn't always go wrong. Sometimes it leaves the cats just fine but it doesn't always and I wouldn't want to take the risk. Especially since really it's easy to control most of the issues anyway. Scratching posts, trimming the nails and then soft paws if trimming them isn't enough.
Now I'm raised in a country in Europe where declawing just isn't done and now living in UK where it's illegal so I confess I was completely horrified when I heard about it being done. From my point of view the claws of a cat is a part of their innnate "cat-ness" i.e like whiskers and ears and their instinct to hunt and the purr etc. So I really can't understand someone welcoming a cat into their home and then not wanting them to be a cat.
Spaying is a bit different because going in and out of heat is very hard on a female cats system (so is having kittens all the time) They can loose weight, are very unhappy and they can get a serious illness as well called Pyometra. Also spaying and neutering reduces the risk of several cancers.
It's one of the reasons responsible breeders only get a few litters out of a female cat and then spay her and place as a pet (usually when she's around 2-3 years old)
If you feel like you really want a declawed cat please adopt one already declawed from a shelter.
