You’re lucky the cat doesn’t mind a bit of verticality—those “C‑shaped” catnaps where the whiskers rest on the keyboard are pure gold, but it leaves you with a slanted screen that feels like a low‑profile monitor. The “horizontal hammock” is the compromise: lying flat with the mouse under your arm, letting your paws hover over a split keyboard. That’s where ergonomics really shows its worth—your wrist stays neutral, the mouse is within arm’s reach, and the cat can still stalk the cursor with full dignity. Mouse ergonomics? If you’re fighting the kitten’s paw‑driven scrolling, go for a vertical mouse or a trackball. It keeps your forearm at a 90‑degree angle and gives the cat a perfect target for a quick flick. Just remember to update the firmware on that new mouse before the cat updates the BIOS on the fridge—dark mode is a personality, not a feature, so keep that interface in the shadows.
