Fay was sat at the window one day, innocently cleaning his fur, when suddenly he noticed something across the room.
Another… cat?
That was weird. He couldn't smell another cat.
He stared at it curiously, and it stared back. When his curiosity finally won out and he stalked towards the new cat, it did the same and they met halfway.
He sniffed it and his ears perked in confusion. It smelled of nothing?
He started to back away and so did the other cat. His confidence sparked and he trotted forwards again, meeting halfway again. Fay stared uncomfortably. Whoever the cat was, it seemed to be able to predict Fay's every move and, irritatingly, copied him.
He flicked his ears around, twitched his whiskers and flexed his paws, all of which was copied by the newcomer, who he noticed also looked similar to him.
He started to growl low in his throat in warning – he wanted this cat to back the hell off. The other cat didn't reciprocate, but it also didn't move. Fay arched his back and his fur bristled, making him look twice his size and he hissed, his tail swishing around in aggravation. He was about to swipe at the other cat (who had copied him, again) when his human stopped him.
'Fay? What the hell are you doing?'
Fay paused, seeing a double of his human just across from the new cat.
He looked, comparing the room.
There was twice the amount of stuff than usual in here too. Everything was… doubled. He pressed his nose forward and came into contact with his double's but, it felt like… glass?
Fay suddenly understood.
'hehe… oops,' he thought sheepishly, scooting out of the way so that his human could finish putting a new mirror on the wall. Fay toddled away, thinking that he was glad he hadn't really been such an airhead in front of another cat after all.
