they pretend they are normal animals but like normal synthoids they use a hologram to pretend to be normal and kill their targets Or just pretend and be normal real-looking, it looks like a weird animal that they are, and that depends on what forms the animal synthoid, and whether it's a dog, a wolf, but not a normal synthoid, otherwise. and he doesn't even have a mouth and he only speaks like an animal scream to seem like he's "normal"
