My Cat Lucy
Cats have amazing hearing almost 10x the average mans hearing. Cats ears can fold almost any way possible, foward, backward, sideways, folded down, and straight up. If a kitty is tired, it's ears will relax.
Folded or Straight?
These ears aren't as folded as much as usual
A cats ears are very sensitive, They're super thin. A cats hearing is way better than humans as i mentioned before, but if the cat is born with folded ears, their hearing will be worse than straight up. There is a breed called the Scottich fold, they get their name from the cats folded ears, yes their hearing is worse than many other breads.

A cats hearing is also how large or small it's ears are. Every cat has differant sized ears, but breads could be known for small or large ears, the scottish fold, small ears, the siamese, known for tall-ish ears, if a cat has way tiny ears it wont be as good of a hearer as a cat with giant ears.
