Man Builds Maze of Tunnels and Walkways in His Home for His Cats

So you think you did well for your cats when you bought them one of those cat trees so they have places to lounge and perch indoors huh? This man took that idea to a totally new level that your cats would be in envy of. 

Greg Krueger has constructed over 100 yards of tunnels, crawl spaces and cat walks for his cats. It's the first time I've seen a cat walk actually made for cats!

Greg has been obsessively building these areas for his four cats over the past 15 years. His obsession made sense to him after he was diagnosed with Asperger’s syndrome.

He loves making these crawl ways and play spaces for his cats almost as much as he loves his cats. They seem to love it too.
