I’m sure Duchess is there waiting for you now, still looking down and loving.
Our other Maine Coon, Snoogie, was also white but he had a few small orange spots and piercing eyes. He and my wife were inseparable. The cat was literally brilliant too. I remember one time we were in a hotel, and were enjoying ourselves well past our normal bedtime, and Snoogie went over, reached up with his big paw, and literally flipped the light switch for the room off. My wife and I looked at each other, and said NO WAY. But each time I flipped it back on, he would wait for me to walk away, and then flip it back off. After the 4th time we said I guess he’s serious about this and went on to bed!
Ha! I had a rescue “mutt” cat, Jethro, that was fascinated with the light switch.
And he “got” the phone. When it rang, he would jump on the counter and knock the receiver off the hook. Then “meow!” It caused some problems if we weren’t home. We’d return and saw the receiver off the hook, and had no idea how long it had been that way.
