I almost had a heart attack because the cat took a poop.

This morning around 8:30am I was startled awake. While I was laying in my bed trying to figure out what exactly had startled me and I heard it... Thump thump thump. It sounded like someone was knocking on the door. All I could think was oh crap this it they've come to tell me something happened to Andrew, I'm not wearing any pants. Yes, that was the exact next thought that flashed through my mind. So, I fly out of bed and to the window in my room. There wasn't anyone in front of my house, but I knew I could see my porch. I'm beginning to believe that I imagined it all and I hear thump, thump, thump. So I assume they pulled up in my driveway far enough that I couldn't see them. I start seriously freaking out I throw on some PJ pants and a hoodie. I throw open my bedroom door and promptly face plant over the baby gate I leave there to keep the dogs out. I get to my front door and open it setting off my alarm system. There's no one there. There's no one in my driveway everything is fine. Andrew is fine. The alarm is still going off though. My phone starts ringing, it's ADT checking to make sure I'm ok. I answer the phone (alarm still sounding). I'm sure the woman on the other end thought was nuts. She could hear my alarm going off. She asked if everything was alright and all of the standard questions. I give her the information that she wants, but I must have sounded shaken because she verified it several times before letting me go. At this point the adrenaline rush I had was gone, the dogs were barking, and I was exhausted. So, I left my poor dogs in their crate and did what any sane person would do. I went to bed. I was laying in my bed trying to fall back to sleep and I heard it again thump, thump, thump. This time I knew it wasn't my door and I decided I was going to figure it out. Turns out that my cats had some how moved their litter box so when they were digging in it it was knocking against the inside of the the piece of furniture that it's kept in. Yes, I almost had a heart attack this morning and for a brief moment I thought the worst all because my cat had to take a poop.
