This is a pet cushion with a built-in heartbeat simulator. It replicates the sound and warmth of a heartbeat, providing a sense of security as if they were snuggling with their mother dog or cat. This product helps puppies, kittens, and pets prone to anxiety sleep soundly and relieve stress. My pet isn't interested in it, so I'm offering it to anyone who is. It's 30 centimeters in size. Batteries are not included. There is no box.
