But yet... people crop dog's ears to please what our idea of what is "beautiful", we chop off cat and dogs' balls, and vets clip a part of a cat's ear off to show it's a feral, but sterile cat.
I understand the spaying and neutering of animals. But the same goes on this situation. It is a procedure that does place the animal in pain. =P Again though, it's a 1 time thing.
