ANYONE handy with a saw and a staple gun can build a simple version of this outdoor fun park for felines, devised by Susan and Dan Gottlieb of Beverly Hills.
The open-air cat run wanders up, down and around the house. Viewing platforms wind up to the roof for bird-watching and sunbathing. Playpens at ground level allow games and snoozes.
Ever since the Gottliebs moved here in 1985, they wanted each cat to enjoy the outdoors as much as they do. But that would have been too dangerous for the animals, which could have wandered off or been attacked by predators.
And too dangerous for the birds. Blue jays, finches, doves, quail, Cooper's hawks, wrens, sparrows, great horned owls and kestrels are drawn to the California native plants and trees that fill an acre at the Gottliebs' rambling one-story hillside house.
"They're too numerous to name them all," Susan says. "They're outside our door all day, every day. We never know who's going to show up."
