The Catstages Hamster Ball is the purrfect challenge for your treat-motivated cat. With two enticing rewards hidden inside - cat treats and a squeaking hamster plush toy - you wild cat can put their instincts to the test to hunt, chase, and capture this elusive rolling "prey." Activate your cat's natural instincts to stalk and hunt while providing the mental stimulation your smarty cat craves. Cats must figure out how to bat, swat, and roll the ball to release the treats stuffed inside, adding energetic physical exercise to the mental challenge. And with a squeaking, feather-adorned hamster within, the temptation is endless. Use with or without the hamster toy to vary the challenge and keep your cat guessing. Inserting the plush toy will slow the release of treats and keep the play going for longer. Give your feline hunter the best of both worlds - an irresistible treat challenge with the perk of an electronic plush toy. Thank us later, human.
