I Still Dont Know..

I still Dont know.. It was septeber a Monday to be descriptive, my mom had left and so I was home alone. My dad had a job interview in LA, so he wouldn't be back for a few weeks. My mom went to go visit her mom for a month, so it was me by myself. Alone. It reached 3:00 p.m. Just playing video games from 5:00 a.m. to 2:00 p.m. I went to go grab a drink, and I hear my cat groaning, and purring. I thought it was totally normal.. Five minutes into my game. I hear my cat groaning louder, like someone or something had stuck a finger nail into its side. "What the hell. Shut up dumb cat." I didn't think to much of it. So I turned back to my game. I think maybe its time to get off. I get off my game and grab some chips and milk and my cat started groaning even louder.. "JERMEY SHUT UP." I turn on the TV to kinda tune out the loud cat noise and watch some cartoons.. As soon as I turn on my TV, I hear a grumbling noise. I hear a screaming noise from outside I go into my kitchen and I see..
