Designs for Felines: 12 Cool Cat Houses

This kitty high rise by global design firm HOK was the "Fan Favorite" of the Giving Shelter Event held to benefit FixNation, a non-profit organization operating the only free, full-time spay/neuter clinic in Los Angeles for stray and feral cats. Note the cat grass and carpeted surfaces for scratching.

Both you and your kitty can be sitting pretty on this bench/cat shelter by Space Int'l. With turf on the the floor and ceiling, elastic strings making up the exterior walls, and pillars of jute, your feline friend can be occupied for hours while you relax up on the roof.

Some of the cat shelters, like this one by Perkins and Will architects, could easily double as works of art — it could be mistaken for a sculpture.

Douglas Teiger of Abramson Teiger Architects used leftover siding from his house to create this elegant outdoor cedar bench with cat crawl spaces underneath. He and his son Jared were on hand to share how much their cats, as well as their two-footed family members, love the design.
