There are very few feral cats left in GG Park - most have been eaten by coyotes.
Good. I had a problem with a feral cat who used to take a dump next to my front door every morning. Apparently a coyote smelled the cat poop and waited for the cat to show up for his morning routine. One morning a daybreak I heard a cat screaming and saw the coyote trot off with his breakfast. Problem solved.
