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'. Our enclosures are also popular for indoor use as well. 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. Our exclusive Pet Door Access accessories can easily match up with a pet door kit installed into a sliding patio door, side slide, sash window, or wall. Take a look around and you'll agree with us when we say we're the BEST outdoor cat enclosure system available!
