1. Both like to be stroked at their convenience, and not crowded the rest of the time. In cats, this is an adorable trait. In authors, I’ve been assured, not so much.
2. Both constantly observe their surroundings. I suspect cats hate to miss out on food, fun or fellow felines, so they always keep an eye out. Authors require gallons of caffeine to stay awake enough to capture human behavior.
3. Both are easily distracted by squirrels. This one is self-explanatory. Squirrels are distracting.
4. Both are always plotting. Cats use a lot of brain power to mold the world in their favor. Writers do the same, except the world they’re manipulating is made-up.
5. Both like tripping people up. Writers spring surprises on their readers to keep them hooked. Cats do it just to mess with you.
