I've seen cats hanging around in various parts of the game, but they don't seem to be interact-able. I like Dogmeat but I'm more of a cat person. Can I get a cat for my settlement?
Well, like I wrote in my earlier (now oudated) answer, you can get a cat on Xbox One and PC due to the addition of the mod kit. Here is a mod I found: https://mods.bethesda.net/#en/workshop/fallout4/mod-detail/1020767
