When Peter Cohen purchased his house in 1988, he noticed that it came with two feral cats that roamed his property. Unfortunately, both cats were hit by cars, and one passed away. After a series of reconstructive surgeries, the surviving cat was brought inside to become an indoor cat. In order to keep his new friend company, Cohen started taking in cats from shelters. Before he knew it, he had rescued a total of 18 cats (all with delicious names like Cookie and Coffee Bean).

In order to cater to the sudden influx of felines, Cohen started a series of renovations starting in the '90s. He installed a set of complex walkways, tunnels, and ramps for the cats to explore and enjoy. To combat the smell, 24 litter boxes are hidden throughout the house, concealed and connected to fans.

Originally white, the house is now painted in blue, green, and yellow: Cohen's favorite colors.

The beautiful catwalks built throughout the house cost about $40,000 to make, but Cohen told Houzz it was ultimately worth it. “Way more expensive than a sane person would build, but I didn’t care,” he explained. “I love my cats, my house and art, so I designed it to be beautiful to me.”
