Our fat cat disappeared the other morning. She never misses breakfast so there was considerable worry. All the closets were investigated. Then at one point I opened a door and yelled, "Is there a fat cat in here?" and a thud followed. She proceeded to keep me company the rest of the day; sat on everything I put down including my big watercolor pad. Just to make a point.
She let me know she was mad at me by ignoring me.
