Cats love to play at dawn and dusk, many owners need their sleep. The Twinkle Ball is fun for kitty to bat and chase, but is quiet so everyone enjoys the evening. There is a touch activated flashing light inside the ball that also doubles as a quiet rattle for added interest in the ball. The raised moon patterns on the ball cause it to move in unusual ways to keep kitty guessing. Twinkle Ball measures 2" in diameter. Imported.
