KONG Infused Catnip Eggs are perfect for an egg hunt all year round! These egg-shaped toys wobble and roll erratically when batted, giving them an unpredictable spin on playtime. A burst of real KONG Premium North American Catnip is infused into each egg using a proprietary blending process, enticing exciting play and biting. Durable, solid material stands up to active solo or multi-cat play sessions.
