I assume when you say criceti 16, you mean the Imac criceti 16?
I have this cage for Porridge and its brilliant, did a thread on it somewhere
Its really spacious for toys and good height if you want a bigger wheel aswell. I use a ferplast shelf in it rather than the original shelf and tubes so i can't comment on them. But its a great price and I adore it
