KONG Cat Sport Balls come as a two-pack of lightweight rolling balls designed for solo cat play. One ball rattles, the other crackles — two different sounds so a cat that loses interest in one still has a reason to bat the other around the kitchen at 3am. Assorted colours, suitable for kittens and adult cats.

Both balls are filled with KONG's premium North American catnip, which does the heavy lifting on engagement for cats that respond to it (roughly two in three). The light weight lets them roll unpredictably across hard floors, triggering the stalk-and-pounce sequence that indoor cats otherwise have to invent excuses for. No batteries, no moving parts, nothing to break.

Owners pick these when they want a low-effort enrichment toy that doesn't need supervision. The two different sound profiles extend novelty longer than a single-ball toy, and the catnip filling means most cats re-engage without needing you to start the game.
