implying humans > all other animals
humans < endangered animals.
And if the pets are rodents and vermins like rats, how you treat them doesn't really matter since buying them for your pet snake or any other predator animal to hunt is a socially acceptable act.
I'm not saying that the value of a human life exceeds all other beings and that all other animals are scum, but that humans have been designed like the way we are. Instead of claws, we use gadgets to defend ourselves, which is the corner stone of a society. We have the ability to think instead of being led by our instincts and other shovelware the brain.exe has given us. Other animals are below us, and we naturally treat them like crap for some reason.
Although putting nails in someones food is loving disgusting and assholish.
