This is my opinion only:
Declawing is purely for the CONVENIENCE of the human. There is no benefit at all to the animal-it actually hurts them.
If people don't like cats with claws, they should get a stuffed animal or adopt a cat that is already declawed, keeping in mind a declawed cat may have litterbox and aggression issues.
Declawing is cutting the claws off AT the first knuckle. It isn't simply a removal of claws. What if a toddler used crayons on a wall? Do we work with them and teach them differently or do we remove their finger tips?
Cats are the same. They can learn. If you have children, if you have cats, you need to make some decisions about what your true priorities are.
I have trouble believing that humans can value inanimate, material goods over
the health and well-being of a living, breathing being.
In most of the world, declawing is illegal. I believe only Canada and the US still allow this practice. Vets make money off it. "Spay and Declaw?" Sure, why not, need another trip to Hawaii

Makes me very cranky!
Thanks for working on hubby

Maybe if you sat him down, drew lines across the first knuckles on his toes and fingers and ask him to imagine living without those.

Off my soapbox now!
