This unique enclosure concept was originated by people who were heavily involved in rescue of pets here in North Florida. They recognized the need for a containment system that is extremely strong, light weight, easy to assemble, and also easy to change configuration or size! These are not cages. CatsOnDeck kits are a solid, built-to-last cat enclosure that will provide a safe environment for your cats and/or small dogs. Perfect for outdoor and indoor requirements. And, should you move, you can easily break it down and take the kit along with you.
