MiniMePets Mod (1.18.1, 1.18.2) turns cats and wolves into miniature players by attaching a nametag. You can have mini-versions of your friends, family, and youtubers that follow you on adventures or help you populate your home. This is a visual change, so wolves will fight on your side. All of them will take their usual food for breeding/healing. Right-clicking will put them down so that they don’t follow you.
