You need a super dwarf retic!! Once you have one, like you said, you'll see why you would pass on carpets. I mean they are awesome still but the colors and patterns available for even super dwarf retics is crazy and I still stand by my words of they are smart and will learn and watch you like they are learning lol. I mean they got their stupid moments too like smashing their face between a litter dam and glass door for half a night thinking something will happen haha. I might end up getting another carpet one day but I will probably go for something like a Bredli or Inland if I do. But personally I see myself getting a Peruvian BCC or another super dwarf retic way before that lol.
