Direct registering walking, too (https://www.youtube.com/watch?v=8riT_b8xbxg). Whiskers to feel air currents, sense prey close to their face, and estimate the dimension of holes. Swiveling ears to precisely locate faint scurrying sounds. Raspy tongues to hold prey. 200-degree visual fields with crazy-good motion detection.

I love my cats, but I often think about how utterly terrifying they'd be if I were prey-sized. (I.e., Adjusting for scales, I'd probably rather take my chances with a Xenomorph than a good mouser domestic cat.)
