I live in a town. Everyone seems to have their cats out running the streets. I just knew I was going to have problems with them. I have security with night sensors. I have watched how the cats come up to my run and lay around watching the pullets. I have seen them spraying around also. They have never tried to attack. At night I watch raccoons , opossums, fox, and once a coyote sniffing around the coop and run. I have never had them stay around and I think it is because of the cats. They just sniff around and leave.
