The Secure Outdoor Cat Run.

This cat run provides your indoor pet with a safe environment in which to run and play outside. The run has a sprung-steel frame that opens instantly, and it compresses easily to form a 62" long strong nylon mesh cylinder, providing a cat, small dog, rabbit, or other pet plenty of space for exercise and fresh air. The run is anchored to the ground by sand pockets (sand not included) and steel pegs; any number of tubes may be zipped together to form longer runs. The run fits easily into its storage bag for travel. 62" L x 18" W. (3 lbs.)
