I don't buy a lot of what is in that article, and this is based on experience. Working for a vet as a vet lab tech for close to 20 years (and almost as much time in cat/kitten rescue, where we often rescue those about to be put down, so I'm well aware of why people return cats..we've had to be at our local shelter quickly sometimes to save a cat that can be rehabbed), and much time spent with him in surgery, declawing is much like any other surgery. Yes, on occasion, something will turn out differently than expected, but that is the very unusual case. The vets I've worked with have never had anyone come back saying something was wrong with the cats paws after a declaw. No way, after years of experience, do I buy that most cats are given up to the shelter because they are biters and that 75% of those are declawed. Not even a fraction of cats returned are declawed. That simply isn't the case. I'm on email lists of many shelters, locally and afar. There are many reasons cats are given up, but I would say biting is on the bottom of the list. Expense, just not wanting to deal with a cat and litter, bad bathroom habits, fleas, scratching children are way up there.
I understand the feelings people have on declawing, especially working day in and out with cat lovers, but a lot of what is said about declawing is someone's cousins, brother, sister in laws mother's friend stoies. Very few first person stories, and I've seen and met thousand's of cat owner's over the years, many with declawed cats. Declawing their cats have enabled them to keep and love their pet. It's not meant to take the place of training, but sometimes no amount of training will do the trick. I would never advocate declawing just to declaw, as I wouldn't advocate any surgery just to do it (and I do spend a lot of time with my foster kittens in the training of using scratching posts, and am usually successful, but then I get them very young before bad habits start)..but after trying the best, a person has to do what is right for them. That said, I have seen much quicker recovery and less bleeding in the laser surgery. If I were having to declaw a pet, I would go with the laser, even though it's more expensive.
