Very, very unfortunate what happened to those kitties, but I'm surprised that an emperor can kill a cat. They're sting is equivalent to a bee sting, but then again I don't know the specifics on how the toxicity affects a cat in comparison to a human. One thing for certain, IF, the emperor was the cause of death for those cats then it would have been the 'curious cat' factor that caused it. Emperors are shy creatures that burrow most of the time and are nocturnal. They usually use their pincers to fend of threats or catch a meal. I know this because I kept one as a pet a few years ago
She never once threw her stinger at me but I did not poke and prod at her either
They are not an aggressive taxon but I'm sure if antagonized they would resort to stinging. I actually had the pleasure of experiencing child birth and rearing with this scorpion. She was wild caught and being of a prolific nature, was pregnant when I bought her. I even took a family photo of the babies sitting on moms back shortly after birth
Very good mom, fed her babies and protected them the whole time they were together..but I digress.... It would be good to find out the actual cause of death in the case of the kitty. Living outside an auto shop makes me wonder if the cats had gotten into some anti-freeze product. Assuming the emperor is the culprit puts future cats at further risk, if infact, the emperor isn't the cause.
