They say that you shouldn't pet a cat backwards.
Well, what about combing one (or two?) backwards? It's winter, and the Gray Cat now deigns to sit on my lap, as long as there's a blanket on it. So I grabbed the comb and started going through her fur. She's a short-haired cat (lynx-point Siamese mix, we think), so going through it the right way didn't take long.
"Huh," thinks I, "wonder what she'll do if I start combing her backwards." Earlier, the White Cat hadn't minded this a bit (the White Cat doesn't care what you do to her as long as you're OMG TOUCHING HER NOW NOW NOW), but the Gray Cat is somewhat...quirkier with her likes and dislikes. For example, she loves being pet with feet. Hands, not so much. Hands are, apparently, icky and gross.
So, I fully expected her to jump off my lap the second I started this experiment. But she didn't. In fact, she just lay there blissfully while I combed her backwards from her nose to her butt. She didn't purr, but she hardly ever does anyway, so this wasn't a surprise.
"Wonder what she'll do if I do her tail too?" I thought.
Yeah, that got her actually purring.
And her tail looked marvelous.
