I don't know that you can compare spaying/neutering to declawing. Spaying and neutering do physically alter the animal, but not in any way that's really noticeable to it. It's mostly a hormonal change. Declawing is basically removal of the forefinger.
If you need a human comparison, we don't consider a woman who's had a hysterectomy to be disabled, right? But we certainly would extend that consideration to a person missing all 10 forefingers.
I'd suggest a different pet if you insist on declawing any type of cat. A dog is a good option, and even though they chew shit up, nobody's talking about removing a dog's teeth, right?
sigh...
While like our DISTAL PHALAGES, it's not the same as cats don't deal with holding things like us.
For an exotic like this it would make no sense, but if declawing can find homes for cats rather than they be put to sleep it's a smart choice.
I have been involved in animals since a baby...professionally during my college years. I have yet to see a cat traumatized or a gimp due to a properly done declaw. The problem is there are a lot of craptasic vets out there. Also not all declaws involve removing the claw itself.
You can train a lot of things but it's nearly impossible to stop a cat from working it's claws. While 9 times out of 10 they pick that scratching post, that one time they pick 100 year old lace or a equivalent can make them unsuitable.
In the end most don't really care for their cats. Even with a declaw you want to keep the rear claws clipped on an indoor cat as they don't get the needed actions to naturally keep them short.
My cats are declawed (4 of them) and most think they are more like dogs than cats because they are social and not always hiding and running away nor trying to bite / scratch at those that want to pet them.
