An Idea For a Possible Joke SCP

So, I have an idea for an SCP that could possibly be a joke SCP.

It's a black cat that's timid and sweet and its anomalous properties appear once someone or something that is aggravated and/or meaning harm to the next thing it sees comes within the same room as it.

That person or creature immediately becomes docile and will try and pet the cat and care for its needs, seemingly made happy because of it.

There could be some tests with some of the more violent D-class, and even some of the more volatile SCPs.

I wanted to post it here to see what others thought of it, as well as perhaps whether it would be a Joke SCP or just a regular one.
