Cats are eaten here in the GSF, yotes, hawks, owls. It's pretty tough on anything that size. If mice are the potato chips, cats are the Snicker bars.
We had a full sized Hawk of some kind hanging around here for a while Spring and early summer. He was huge. No cats or other vermin to be seen. Noy seen the Hawk in a good while and the vermin were quick to come back.
