Aren't these cat icons just too cute?!
If you look closely, you can see that the cat ears are still there, so it's likely that the cat's original ears haven't been transformed into cat ears; they still function as ears.
Also, the cat ears are clearly the same color as the hair, so perhaps they're formed by altering scalp cells?
In other words, these cat ears have blood flowing through them, so they're warm and have nerves running through them, which means they're likely to move up and down like real cats!
