Some people may believe there are no streets inside a home. They would be wrong. We kitties have what's known as a Cat Superhighway. Actually we have two.
The first one is at the intersection of the first and second floors overlooking the kitchen (why yes, we do sometimes give our mom heart failure as we race down this first superhighway. That's half the fun!)
The second one was installed in the guest bedroom and is a series of shelves we love to traverse.
Cats are built to live on three planes, not just two. So when you think of places for your cat, think height as well as length and depth!
