It used to be very common here, I would say nearly 100 percent, but it is definitely going down. Hopefully soon it will be uncommon. The vet clinic I take mine to will do it but they try to discourage it. They explain how it is done and offer behavior counseling to help with the destructive clawing. I do know that when they declaw they will only do kittens not adults except for a medical condition. I think kittens tend to adapt better to it than adults.
