Thank you all for your kind words. It really helps. I think I will take Kathryn's advice and tell you about my little Slinky.
We adopted him as a kitten from a local shelter. He was a stray that had been found stuck in a vending machine. Due to his traumatic beginnings Slinky was initially terrified of people. The first few months with us were spent mostly under the bed. He slowly emerged and began trusting us. He would come on to the bed and night and have what we called 'walk around purr purr'. He'd keep moving while we pet him and he purred like crazy. He eventually came out of his shell and became a major part of our lives. He turned out to be the happiest cat I've ever had. Dh and I always said that if we could be one of our cats we'd be Slinky because of his happiness.
The first thing I did every morning was open the curtain so he could see out from his sleeping spot on the back of the couch. He would thank me with a little meow. That last thing I did every night was give him some cat treats in the bedroom. He would make sure this happened with many persistent meows. Even though I get up earlier, dh is the cat feeder. At his slightest stir in the morning Slinky would dash down the hallway and start meowing until he got fed. Dh gets easily distracted so Slinky kept him on track. "Meow! Don't check email. Feed me!" "Meow, why are you going into the office? Feed me!" The other cats simply sat on their mats a waited while Slinky did all the work. Feeding time will never be the same.
He was a cat who much preferred to be with his humans. Sometimes he wouldn't even go out unless we went with him. The other cats, who aren't let out as much as he was 'cause unlike Slinky they cannot be trusted to not leave the yard, thought he was nuts. "You mean they'd let you out and you won't go?" I'm sure is what they would think.
Our house is now so quiet. We will miss him forever. He was a kind and sweet soul.
