The tennis shoe material of the KONG® Shakers Cuckoos arouses tugging and shaking impulses for long-lasting fun. A deep squeaking sound throughout the body enlivens interaction, while crackling sounds stimulate instincts. The playful bird's long body and a reinforced lining ensure that playtime fun lasts for a long time. Assorted colours. Note: Please never leave the pet unattended while playing. No toy is indestructible. To prevent injuries, the toy should be checked regularly for damage or loose parts and replaced if necessary.
