Greg Krueger, a 49-year-old man from Minnesota, loves cats so much he's built a cool indoor playground/house for his four cats!
Over the last 15 years, Krueger has spent time building and renovating his house to include little nooks, crannies, and "cat walks" for his cats to play and explore.
Krueger, who was recently diagnosed with Asperger's, told CBS Minnesota that he thinks about the project constantly.
“I think about it constantly, I can’t fall asleep,” he told CBS Minnesota. “I’m still thinking about it, thinking about the design. I wake up, I’m thinking about it. I’m thinking about it all day at work.”
He's carved out holes to form shapes that include Charlie Brown, a cat, a bluebird, and many more.
What's more, the cats get their own mini rooms with beautiful lighting as well.
Basically, Krueger seems like the coolest cat dad in town.
