Allow me to indulge is some wee cat tales, and also tails. This links to writing in a roundabout way, I promise.
All three of our cats are, well, cats. This they have in common. They have whiskers and pointy ears and fur and, yes, tails. But here is where they differ.
^Clara, the oldest, has never done a bad thing in her life. She never sharpens her claws on anything but the cardboard we provide for such purpose; never nudges anyone off their food bowl; never attacks the others, and has never met a person she doesn’t like. She does not assume you want her on your lap, so she looks to your invitation and will leave with the slightest sign you’ve had enough. She’s the best (and only, actually) real mouser, and has kept us rodent-free as fee for her care.
She is the cat you want if you need one working feline.
^Our youngest, Nougat, is a senseless goof. She gets herself into spaces she can’t get out of, considers everything a batting toy, and talks all the time. She can hold a continuous conversation for half an hour, as long as you keep responding. Her sentences are as varied as they are entertaining. She prefers your company and play to a tasty morsel every time. Folks who think cats are just food motivated, haven’t met Nougat. “Food? What food? Play with me, I tell you. Meow-meow, I’m talking to you!”
This brings me to writing. Yes, they’re all cats, of the Felis Catus species. But they are individuals. A good reminder not to have generic characters when telling a story.
