She is the most interesting cat.
Sometimes she sleeps with me all night and then I find her napping in my bed when I get home from work.
Other times she goes out all night doing who knows what and comes back in mad. Like I made her go outside all night.
A few summers ago, we had a woman stop at our house on her walk with her dog.
She asked if Gloria was our cat. Yes, we said.
She went on to say that Gloria aka "Sunshine" had been staying at her house at night. She had a bed, some food, and some toys. No wonder she was "out all night".
