Peter Cohen (owner of Trillium Enterprises in Santa Barbara, California) has customized his house to be entirely cat-friendly. From walkways to tunnels, his whole home is filled with feline-specific features that his cats can enjoy.
A high hide for cats."I am so going to install this in my house for my kitties.especially since I have a couple older cats that do not like our dogs. This will be perfect for them to hide, look out, get away, and just be in peace.
Made a cat door tunnel thing in my wall because cat doors are ugly.
