My family has have numerous cats. Our neighbor at one point was a vet and convinced us to not declaw one of our cats. She was a bitch. She was spayed at the same time as the rest of them but she would not sheath her claws when it came to Dad's chair, our couch, our arms and legs, and my stuffed animals. I had to shut my bedroom door all the time. Spraying water, using a fly swatter on her, noise, smelly stuff (more than one kind or brand but enough to make us hate the smell of some of them too), sticky tape, covering the couch and chair, EVERYTHING recommended, we did. Maybe we were unlucky to get a cat with a bad attitude. But ever since we've gotten them declawed at the same time as spaying or neutering.
Our 3 yr old cat is fine with no front claws. We did not remove her rear claws. We had it done at the same time as she was spayed and she layed around for 2 days after being spayed. They do not (or at least at her vets) bandage them all up thoroughly. I do not know if they did the lasor method but she had almost no visible sign of being declawed. We picked her up the day after. She had liquid stitches on her paws. We kept oatmeal in her litter box instead of litter for a week. She was running and playing within 3 days and had no change in attitude - except when it came to going in the car
but I think that would have happened with just the spaying.
