This ZenCrate Smart Anxiety Relief Pet Crate is the first “smart” dog den that reduces anxiety caused by separation, loud noises, and storm phobia, even when you are not home to care for your favorite four-legged friend! This Smart Anxiety Relief Pet Crate is designed to work around the clock, 24/7. Its special sensors know when a pet enters and starts working its magic by playing specialized music and creating a soft gentle air flow. Once your furry friend is anxiety free and decides to leave the crate, it will automatically turn itself off.
