Rather than hijack the threadthat prompted this, I don’t believe your information is correct, BiblioCat.
From this site:
I called my vet clinic, and the receptionist assured me that just the claw is removed. She didn’t know anything about the knuckle being removed, and recommended I talk to the vet (who is busy with appointments) for that information. I called the Calgary Humane Society, and they informed me that there is no procedure for de-clawing cats that does not involve removing the first knuckle of a cat’s digit.
I cannot find any information that indicates that laser de-clawing is anything except onychectomy, which is the removal of the first knuckle of a cat’s digit. If anybody has a cite that laser de-clawing is removal of the claw only, not the phalanx, please share.
