I may be an evil genius in disguise.
Take an ordinary empty toilet paper tube. Fold in the sides at one end, so you have a reasonable seal. Put a generous pinch of catnip inside the tube. Fold in the sides of the other end of the tube.
Give to your too-smart-for-his-own-good cat, and watch him nose the thing around the kitchen floor for half an hour, yelling at it and occasionally bunny-kicking the shit out of it, but not managing to open it up.
Giggle evilly when he dances sideways at it and looks at you imploringly. Giggle harder when he noses it under the fridge and demands that you rescue it. Rescue nip tube. Give back to frustrated cat. Retreat to comfy chair to watch the show.
ETA: I accidentally some words.
