Yea, I wouldn't even know about it if it weren't my pet or my friend or whatever.
All I am saying though, is that as a player, the fact that you know those critters CAN be sentient, and therefore killing them COULD potentially be murder, they CANNOT automatically be KOS for you. You must make some attempt to determine if they are sentient - asking them to speak if you say cogni is the threshhold for sentience.
asking them to do a flip to prove they are a player. whatever it is. They cannot be KOS
