I'm looking into getting a ferret, not anytime soon but in the near future, I personally never liked the visual look of a cage. Now my question is, would be a good a idea to build what basically amounts to a massive two tier natural terrarium for him? Think of some of the more elaborate ones for reference, like real foliage, mini waterfall, tunnel system, digging area, etc. think of some of the fancier reptile enclosures but scaled and modified for a ferret. Of course I'd take it out of the cage a majority of the time for play and the like, i just like the look of a natural looking mini forest as opposed to a drab cage and want to know if that would be suitable for a ferret
