norway has no such problems and they don't spay/neuter their animals on mass, https://jennifermargulis.net/norwegians-believe-spaying-or-neutering- a-dog-is-cruel/

also similar logic could be used against humans, if an alien race came and enslaved us would you be fine with them cutting of your genitalia for "your own good" ?

Norway doesn't spay/neuter their pets and they have no problem with overpopulation each owner is responsible for their own dog (more about it here: https://jennifermargulis.net/norwegians-believe-spaying-or-neutering- a-dog-is-cruel/) ) besides couldn't the exact same argument be made for humanity ? would you just say it's the "ethical choice" if an alien race came to our planet and cut off our genitals to stop overpopulation ?
