Just a bit of research before i start my diy building. We have 3 corns so im thinking about getting a 3 draw bedside unit or dressing table or something of that sort about 3ft wide to convert. Would this be large enough as each "viv" would only be as high as a draw, if that makes scence. They wont be going in straight away as they are still young, approx 8mths old and about 1ft long or just over.
