Cause of Poor Sleep

For the past year, I've been tracking my sleep using the Fitbit Blaze that syncs to my cell phone. I typically wake up in the middle of the night multiple times for no reason. Now, I figured that it was because I had sleep apnea or something. Instead, I read an article that explained everything and it caused a moment of eureka for me: "sleeping with your pets". My cat!!! Yes, my cat wakes up all the time. Every time she moves, the bell on her collar rings. She also throws up furballs in the middle of the night. Now everything makes total sense as to why I'm sleep deprived. Time to get rid of the cat! No, just kidding. I have to figure out how to keep her out of my room for now on.
