It’s probably a good idea to report it to the Sheriff or the Fish and Game in case they start having a problem in the area. The Fish and Game will act if pets start disappearing.
Illinois likes to pretend that there are no cougars around here. However, there have been several sightings and prints found 30 miles North of where I live, and coincidently on the same night, and a few nights after that.
The police from that town were riding through the town perched in the extendable bucket of the town’s fire truck “looking” for the cat. Yeah, I’m going to call the sheriff.
There is an abundance of deer in the forest preserves, so I don’t think they are prowling around for food.
