Scaredy Cat

This morning, I went to the upstairs room. There was a family of stray cats under the bed. I was already scared enough, then one cat hissed at me and was jumping on the shelves! I totally jumped out of my skin and fled for my life! (Yes, over dramatic, but I was literally scared that it might attack me!) Do you know, if I leave them alone, will they eventually leave?

I got 3 hours of sleep. Am I just more edgy? Or does this stem from the ongoing relationship with Shadow (Mel's childhood cat which would attack me when I'd spend the night at her house)?
