Sharingan Wights

Shisui can create creatures who can stalk and spy on anyone he commands them too. Each of these creatures bear his within their eyes, allowing him to see what they see and even cast additional illusions through their vision. Because the creatures are illusions as opposed to real animals, they do not make any sound and appear as a blurry image if anyone would look at them directly - something that can easily be missed during the night.

Aligning with Shisui's character, these creatures are generally cats but he can also creature air- or sea-born wights such as crows or salamanders should the situation call for it.
