Our cat, I believe had a feral start. Most of the time she's good, but has her moments of ferocious hostility. She's a big cat and it hurts when she chomps you on the calf, foot , arm. She came declawed in the front. Otherwise I don't know if we could keep her.
I have both and oddly they all get along. Dogs obey, cats defy. That’s their personality, but all of mine are sweet. The two tiger cats are bad-ass hunters, so I really don’t have any rat/mouse/snake or gopher problems. The dog is a Walker Hound and keeps any squirrels/coons and possums up in the trees.
