Cats living in apartment buildings are known to fall and injure themselves.
Which level can a cat fall from, and reach terminal velocity, and receive a less sever injury?
7th floor/story or higher
This is because they reach terminal velocity, they relax, and will flatten their body outwards, and spread the force experience on their body more equally
