There was one case of uncommonly lots of missing pets one day. Upon investigation I found out it was poachers and other thugs hired as a mercenaries by Beastleap Program working for Imperial Dominatum Nation. Feeling like legendary Shigeo Ijuin, I opted to destroy the criminals with their own sick fun of illegally forcing pets to kill each other - by using my Undershadows! Then all the pets that survived till my arrival were soon returned to their homes.
