What Is The Difference Between Clipping A Puppy’s Ears Or Tail And Declawing A Kitten?

I was raised on a ranch, I helped brand cows and castrate sheep. I just bought two Bengal kittens and while I understand that the procedure is brutal, I have an older cat that I had declawed and she never missed a beat, she dose everything she needs to do with her back claws. If declawing a kitten is so horrible and mean why do people clip some breeds of puppy’s ears or tails? How is that different? Any insight anyone might have on adjusting from a ranch girl to a city pet owner would be appreciated.
