People do that to cats all the time thereby saving their
precious furniture at the expense of the cat's primary
defensive and offensive weapon.

Bull****. A cat's primary weapon is it's rear claws. The fronts
are merely a warning of things to come.

Cats without fronts have difficulty running away from trouble.
They want to climb but can't so they get caught and beaten up a
lot.

It's a barbaric practice. Turning a fine animal into a powder puff is
an awful thing to do.
