I have never seen that many cats together in the wild. Since studies show that a cougar kills a deer sized game every 7 days. Eight cats would then kill about 432 or more animals a year, just for this group. I am sure that this will effect the pets, livestock and wild game numbers in this area. They are NOT vegetarians! An Idaho game biologist told me that the cougars are having problems because they only eat what they kill. The bears and wolves come in and eat the buried animals before the cougar can finish their kill off. They then have to kill another animal for something to eat. He had to determine what species actually killed the game.
