We had farm cats in coyote territory without issue. We never lost one to coyotes to my knowledge. You just need to ensure that you also have coyote deterants like an assault donkey or a llama. Having a big guard dog also helps. Basically, anything that would protect your livestock will also protect the cats. If there are enough threats to coyotes in the area then the coyotes will steer clear.

In our case it probably also helped that mama farm cat was a monsterous maine coon who I once saw literally beat the shit out of a full grown rotweiler that got too close to her kittens. It wouldn’t surprise me if she had been hunting coyotes for sport.
