They tend to give the barn cats a decently wide berth, at about 12 pounds tops the greys aren't much bigger than the cats. I have no doubt they would take a kitten or smaller cat if unaware but the full grown ones seem pretty safe. The amount of work and injury needed to take an alert cat is probably not worth it on the risk analysis tables. Great Horned Owls and coyotes are the main animal predators of cats in these parts. Coyotes seem to relish them quite a bit.
I also have no doubt they would take a small, clueless dog the size of a grey or smaller as many of them do not have much of a killer instinct, the ability to deliever a good bit, or the mobility needed to defend themselves. A Jack Russel would probably be an exception only due to its spastic nature which would probably confuse the fox.
