Alrighty then.
Maybe one or two...but you get a pack..you can expect more that a few feral cats to go missing.
A few years ago, for whatever strange reason, we had a huge explosion in the coyote population. Accompanied by an infestation of feral hogs, some of which were the size of a small dune buggy (no exaggeration). Things got pretty Dodge City, lol.
A neighbor of mine got two Catahoulas. They made short work of the coyotes. I almost, but not quite, felt sorry for them. I still hear a few in the distance but not close to my house. Although quite capable, they were aided in the feral hog invasion with some human intervention. Most skidaddled back to the river bottom. Still there, but not invasive, so far. Oddly enough those two Catahoulas don't bother domestic pets or people. I call them Dirty and Harry. I think he gave them some sissified names.
Those darn things can climb trees.
