Ninja cat.... there is a story to this...
One of my coworkers woke up a few weeks ago to a cat that somehow broke into his house in the middle of the night and made it's way up to his room. He got quite a scare being woken up to a cat pawing at his face. Needless to say the cat was kicked out of the house
I dubbed him ninja cat, and he has obviously been embarrassed by his failed assassination attempt because he hasn't been seen since.
