The Orange Tree House catio is a masterpiece (see amazing video – must click into post first). The enclosure reaches more than 20 feet up into a gorgeous hundred-year-old tree. The Sherman Oaks enclosure gives Hannah, Trudy, Dottie (in photo), and Harlow plenty of platforms to navigate to via the tree trunk to watch the endless visiting squirrels and birds at close range. There’s also a 45+ foot run that allows the cats and kittens to access the structure 24/7 from the house. Finally, note the sandbox / litter box in the middle of the run. AWESOME!
