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?
As of the latest DLC, the Wasteland Workshop DLC, you can build a cat cage in any settlement to capture a cat.
Here’s a video tutorial explaining how to use your cat cages. Then you can have cats freely roaming around your home!
