The cats we don't have

Rupert hadn't a cat either. Nor even an imaginary one. But there's one ginger with only one ear and a half. Sometimes he leaves the left-overs at the back door. Sometimes the cat comes. His cat doesn't have a name, either. But he owns it and knows it. Maybe only knowing, because nobody can claim ownership with a cat. Just a path you walk together. But Rupert knows his ginger unnamed cat. It's like Lucy, unfriendly and disdainful. Walking on the back of the hammock, jumping over the windowsill, teasing Rupert when he's trying to take a nap.
No, you never own a cat.
Maybe, if you are lucky, a cat owns you.
