During the evacuation of Skure mentioned in PSII, a lot of people left their pet Musk Cats behind. Why do you think they did that? Surely they would have thought that any gas leak that was toxic to them would be toxic to the cats, too. Did they forget the cats or were they forced to leave them behind for some reason?
If you were living in Skure when the evacuation happened and had a pet, would you have left it or taken it with you when leaving the planet?
