The ears should always be placed above the part of the head it overlaps. You can do this with the z-index property.
z-index is a property you can use to define the order of overlapping HTML elements. Any element with a higher z-index will always be positioned over an element with a lower z-index.
To see z-index in action, set the z-index property of the left ear to -1.
Your .cat-left-ear selector should have a z-index of -1. Don't forget to add a semicolon.
assert(new __helpers.CSSHelp(document).getStyle('.cat-left-ear')?.zIndex === '-1')
