In business since 2008 CatsOnDeck manufactures unique modular and easy-to-assemble cat enclosures to provide your cats with a safe outdoor experience we call 'Lifestyle Enrichment'. CatsOnDeck offers many accessories and the modularity of the design means you can easily increase size or change the configuration at any time. Weather is not an issue for our enclosures. We use high-grade materials to provide a top quality product that will last many years. CatsOnDeck works well on decks, patios, and lawns. It's a perfect solution for indoor cat containment as well. Our exclusive access via pet door accessories can easily match up with a pet door kit installed into a sliding patio door, side slide window, sash window, or wall.
