Getting a vasectomy or tubal ligation, or having a hysterectomy is a bit different than having one's first joints broken and cut out, which is really what declawing is all about. If pets were not spayed and neutered the population would be a much greater problem than it already is with irresponsible owners who do not do so. Not getting the urge by going into heat twice a year is a bit different than the daily reminder of having no claws with which to climb and/or defend.
