Rule of thumb in my opinion, if you have to perform body modification on an animal, it doesn't sound like it was ever worth keeping. Clipping bird wings, deforming monkey thumbs, declawing cats, etc. make me cringe bad.
People sadly do all those things. People declaw cats because cat claws can get sharp enough to get into fabric, and the people who declaw their cats either don't realize cat claws are a part of their fingers or don't care. People dethumb monkeys because it hinders their ability to weaponize their surroundings, again because all they seem to care about is showing off their pet.
Personally, I would caution against pet castration/neutering/spaying even though it's not up there with the other things. When it comes to this, you're just trading some problems for other problems, and it still says a bit about the act of owning them.

Castration is pretty much a necessity for some pets. Unless you want your house to stink like a crossover between a zoo and a public toilet.
