I'm just wondering if anyone has ever tried rats in Iris tubs. I notice Eric has some Iris tubs that he says are good for rodents (the CB series in particular). I'd love to have a rat rack to make space more efficient but I would really like to have a clear tub so I can see the rats and I like the idea of a deeper tub for them. Anyone with experience with rats and Iris tubs? I would think they'd work fairly well as they are super smooth inside so there's little to no ridges to promote chewing like there can be in Sterlite or Rubbermaid. I know Iris is a lot more money than other tub options but since I don't have 100's of rats it's not a huge issue.
