It isn’t spite
VCA Animal Hospitals is direct about this: cats who knock objects off shelves and tables are exercising their inborn need to hunt, finding “prey” wherever they can, including on your shelves and tables. The behaviour borrows the same predatory sequence cats use on real prey (stalk, pounce, bite), just redirected at a pen that happens to roll invitingly.
The second reason: your reaction
There is a second, less flattering mechanism. A cat that knocks something over learns that it reliably produces a reaction from you, and even a glance up from your phone counts.

“That’s a second reinforcement loop stacked on top of the hunting instinct, and it is entirely your fault.”— Doctor Agatha
What actually helps
VCA’s guidance for redirecting predatory play applies directly: give the behaviour a legitimate outlet. Toys that roll, and things she can genuinely stalk, chase and pounce on, satisfy the same drive your desk ornaments are currently absorbing.
- Treat play as a daily need, not an occasional bonus
- Use real prey-style play: a wand toy, a ball that rolls unpredictably, even a treat puzzle that makes her “hunt”
- Rotate the toys. A toy left out permanently stops registering as interesting prey fairly quickly
