Your hamster isn't truly living until it is living inside of Katja's hamster mansion. The single-named German pet-lover recently converted a three shelf Ikea bookcase into the ultimate hamster home.
Katja's hamster mansion features everything a hamster could ever want or need. Small caves are located on each floor with grooming sand on the bottom and a feed and litter box on the top floor. I never thought I'd see the day when a hamster was living better than I was.
