It's Purrfect

Select your spirit chunk

Yes, well, you see there's a tiny white spot on the bottom of it's nose/top of his mouth, and the other one's white stops below the mouth... So what we have here, is not two identical cats, but your cat and a cat that put on a disguise as your cat - that escaped from the mirror world. So, we'll need to take them both and merge them again. Please hand them over at once.

Hahahaha :D
