I'll make this the short version of the story. A week ago a family of wild cats decided to move in under my deck. I told my son to stop feeding them, the boy has a love for all creatures, and explained that cats are predators and we have chickens. This morning i went out to feed and water the chickens and saw a rat in the run. So to my dilema, since the chicken coop in a couple feet off the ground there is a space under it for in my eyes now either a family of cats or a family of rats. I have wire fence barried to keep critters from getting in the run from under the coop which after today is going to be a cement wall because i see rats will chew. So i guess my question to the experts here is....are the cats really going to be a threat to my chickens? The coop is pretty predator proof, well i guess i should say large predator proof, so i dont think the cats can actually get in. So would i be better off letting the cats stay to hopefully get rid of the rat problem?
