hey, at least Pippy gets the idea of trajectories - he looks at where the object would be, had it been thrown. My parents' cat (RIP aged 18.5) never grasped that, and would stare at your hand after the object had gone.
This cat is waaaaay smarter than my cat, who resembles mentally and physically one of those things a few years back, the prickly household things you could get at the stores, where you could wipe your shoes on them when you come in the house? Like, a hedgehog stone with bristles on it? Yeah.
