Pet Cats? (Hear me out..)

I think iron golem should have a little animal near/ on them. Like a small cat that runs around the iron golem and interact with villagers. Or, I think that the iron golem should have a parrot that sits on their shoulder and helps to guard the village. Neither of these would be hostile, but they would interact with the golem/ village. (The cat could also have a skin that kinda matches the villager, like a gray striped cat. After you kill the iron golem, the player could tame the cat/parrot.)
