Read this part over again...

Why kill an animal needlessly and just throw it in the trash? It's a waste of a life.
It's not a pest that has come in from outside and chewed holes through my walls and invaded my house that has been living on parasite infested trash and rat poisons for it's entire life. It's an animal that I've raised myself for the purposes of feeding to my snakes. Sure, it's possible that in the few days it's been free it could have ingested something injurious that would put my snake at risk, it's also possible that I could win the lottery tomorrow and I'd be able to retire to my own private island in the south seas. I think both have about an equal chance of happening.

To me, it's just not worth being that overly cautious. If I started to think that way it would drive me insane.
