We already had purchased a stand alone catio from catsnets we love for our 3 girl cats. But a stray boy kitten came to us in need...and of course we had to keep him. We wanted them to have more space outside, so we came back to this cite and ordered netting to actually in close our back patio. We created a tunnel as well to get from the stand alone catio to the patio. They love. The netting is great. Its so much easier to work with than deer netting. We also utilized the videos on this cite for using the guide ropes. It took a few days but it all came together and our cats just love it. We installed a pet door for the window so they come in and out safely whenever they please. Elsa, Anna, Luna, and Rufus approve!
