I'm very very casually working on some three-eyed and other variant cats for adoption. For the ones here, instead of one three-eyed cat, it's three one-eyed cats! Or well, 'cats' in the loosest sense. They can NOT be separated. They can move independently, but they always stay within a certain radius of each other. If you were to take one away, they would all start to emit an ear-splitting, high-frequency sound.
