Yeah my cat died too.
It's just go too troublesome trying to keep him alive. Why in the world the Crocs would leave combat with me, take a hit to run across the field just to kill my poor lil kitty cat is beyond me! I would have redone the battle but it seems it is destined to die if the game AI is going to do that. So I wiped a tear and moved on.
Hopefully they fix that later because I agree there is something more too it.
