I've been using one trackball or another, usually a Kensington Orbit since they became available, for the majority of three decades; the only times I've had to buy a new one were when I needed more for extra computers or when new technology became available (such as when optical became a thing). I've never had a trackball ball wear out or even show signs of wear.

Actually, that's not 100% true. I did have one Orbit just stop consistently responding to input. The ball was fine, though; in fact, I'm pretty sure I still have the mouse and could just put the ball in a new unit.

Mine still works, it's an old trackball my grandfather bought for himslef in the late 1990's.

I do believe the comment about the ball wearing out was what humans refer to as "humor"

If the cat is on your wrist and not really on your fingers those will work, but if the cat's on your fingers then you're just as SOL. Even then you still need a bit of palm movement.
