I've heard that other than chickens (damn those immortal chickens...I'm still traumatized from accidentally bombing one in Ocarina of Time), all animals die. I know they have some sort of hidden life meter, which increases and decreases based on actions. So I have four questions.
-What prolongs the life of a piggy?
-What depletes the life of a piggy (besides time)?
-What prolongs the life of a butterfly?
-What depletes the life of a butterfly (besides time)?
Another thing I'm wondering about is the fact that I treat all of my backyard pets equally, yet Kaylee the butterfly died yesterday and the other two are still kicking. Why is this?
