I got to thinking recently. My cat is pushing 15 years old. I think I got him sometime in 1996/7. I've had this cat longer now than I have not had him. I thought to myself, do I value his life more than that of a human's? And I think I do... at least, to an extent.
If someone had to decide between saving one of two people, and they chose to save the person who was a friend/family as opposed to the complete stranger, would you think they chose wrong? And would the same hold true if the friend/family was a pet and the other person was a complete stranger?
