This kit includes both the Cool Pup Crate Fan and the Cooling System in one complete package. The Cool Pup Crate Fan provides a steady cooling breeze for your dog at home or while traveling. Two retractable arms allow the fan to be hung on a cage, crate, or any kind of pet carrier. The Crate Fan Cooling System for your Cool Pup Crate Fan keeps your dog extra cool during warm weather. The system comes with a specially-made ice pack that securely attaches to the front of the fan. The result? Instant air-conditioning for your dog.
