Ive seen very docile raccoons go completely crazy by just showing them the foot of a killed raccoon, idk if they react to the scent and see it as a friend/ foe or if they just hate seeing others dismembered but there is definitely a huge reaction.
I've had 2 in two weeks. I've decided I'm going to start hanging there feet around in random places, raccoons hate seeing feet and tails from other raccoons hanging around
