Greg Krueger has been building the ultimate cat playhouse in his home in Minnesota for over 15 years. He says that after he was diagnosed with Aspergers at age 49, his obsession with building walkways for his cats began to make sense. The level of detail involved in his project is so impressive. Its over 100 yards long! The cats even have lighting and padding so that theyre comfortable in their little chalets! If you could make a kitty wonderland, how would it look?
