hanging body

Hi, i want to create a rabbit or maybe a cat where someone grab it on its neck and slowly swinging left and right. I want to create or to simulate the flex of body while it will follow /interact to the movement of the swing. What is the best way to achieve this fx ? i don’t need to create a super detail movement, just want to get the basic correct interaction only. Is it possible without using bones ?

Thanks

Tbh I think the best approach here might be to make a simple rig and animate it by hand. I think a soft-body approach would result in the animal looking more like a rubber chicken than a real organism with muscles and bones.
