I have only not kept a cat once. And if the situation was not 100 percent what it was, I would have never done it otherwise.
We moved two hours away and our awesome cat, Klaus, was a very unhappy kitty. I won't go into details, but he was clearly miserable and we tried everything we could think of to change the situation for the better. Nothing worked.
My parents suggested that they take him for a trial session and see how he did. They lived in our old neighborhood and had a much quieter living situation. Klaus was so happy there and my parents clearly missed having a cat. (We had one when I was growing up.)
We missed him terribly but when we went to visit it was so nice to see the old Klaus back. He never completely lost some of his skittishness but it was a full 180 for him. And when my father died last month, my mother said she didn't know what she would do without Klaus. He has been company and comfort to her.
Pets are not last years shoes that you can toss to the back of the closet when you are tired of them. Why can't people see this?
Dogs have owners, cats have staff.

And there are some humans here too!
