We have a stocking for ours. I can't bring myself to throw out the one for our last dog. She was our first family dog and we had her for over 17 years.
I have initialed ones for my cats. When a couple died rather than buying new stockings for their catnip toys and treats I just named my new cat with the same initial.
I treat my two cats very well. They have their own bedroom, and all the good stuff. They enjoy their bottled water, their own deck chairs under an umbrella. I even made them their own shelves and steps on the office wall so they can lay in the sun and look out the window.
