Agree with the others - I have the Barney for our Syrian
He was in a cage the size of the Hamster Heaven before - it was ok but he needed a 12" wheel and it took up most of the cage! An 11" wheel fits fine in it though. The Barney is good value as it comes with a good sized house for a syrian and a shelf. If it's too big then the Alexander or Savic plaza have a slightly smaller footprint.
