I WAS going to do this when I got my kitty 3yrs ago.
The vet didnt even say anything to me when I asked except the cost of course.
In reality declawing is CRUEL AND UNUSUAL. Even for indoor cats.
Its one thing to say, well my cat is indoors I dont want clawed up furniture and they wont be climbing trees, they dont need their claws.
And its another to say that with the knowledge that cats claws are NOT nails like our fingernails. They are physically attached to the foot bones with ligaments and muscle, allowing for the familiar retracting cat claw.
Removing the nails is like cutting YOUR fingers at the first knuckle. No lie. WOuld you want to walk around without the tips of all of your fingers and toes?
