Kitty Camo Coil by Petstages satisfies kitty's natural need for a safe retreat. The sturdy mesh construction provides a safe and secure sanctuary for resting and observing. This tunnel is open at both ends for easy entrance and exit. When kitty’s not using it, simply collapse and tie up for storage. Most cats stay inside all of their lives, separated from the stimulating, engaging activities that are naturally available outside of the house. To help address your cat's instinctual needs, Invironment products offer a variety of natural materials, textures and activities to provide the Invironment that kitty craves, making them a safe and happy cat!
