And apparently Madison has a winter litter box and a summer litter box. When we first moved in Madison was relegated to having her box in the 3rd bedroom because I wasn’t sure how she was going to react to 3 floors and I knew I didn’t want a litter box on the 1st floor. Once we were in the house for about a month I started letting her into the basement because my ultimate goal was to get the litter box moved to the basement for good. So Madison would go into the basement when I was doing laundry and cry when the basement door was shut so she couldn’t get in…
Once the crying started … I opened the door for good and she was basically living in the basement (I guess because it was the coolest place in the house) and the upstairs litter box was abandoned. FF to November and Madison gradually stopped going into the basement… and was once again an upstairs litter box cat.
Imagine my surprise when I was in the basement last weekend and glanced at the litter box …. Lets just say it was ready to be emptied 
At least the lack of business in the upstairs litter box now made sense 
Great Story.
