We neuter male cats so they don’t spray piss everywhere and spay female cats so they don’t go into heat and scream incessantly to be let outside.

Both procedures seem slightly more invasive than removing a scent gland in a skunk, given that it removes the sex organs that secrete hormones and changes their behavior for the rest of their life.

It’s possible that a skunk gets anxious when it tries to spray and nothing comes out, I can’t say I’m an expert in skunk behavior, it just seems less invasive than spaying or neutering to me.

No, we neuter and spay so we are not overrun with feral cats. Not to control where they piss.
