The wood is of course unfortunately softwood, and also needs to be only painted with sabberlack so urine does not pick up the wood and stinks, and I have on my model also for the little mouse "achievable" make and the pages attached aluminum mesh to prevent them from not gnaw through the wood. what I think is a shame that the drawer is very low, and I have my simply screwed tightly, because I'll never use it anyway! my mice may dig!
So, I can only recommend to buy! the chamber of horrors that was described below clearly applies not (more), since the production of improved cage in my opinion! The instructions are easy to understand and certainly involved a fun for all. I would still to advise the rough edges file off, because one can never be too careful with such little creatures, and I would also sides and back wall with aluminum mesh or hardwood provided so that small does not occur to the cage reflected in all items to decompose! AND: sabberlack is a must for anyone who does not wish that the whole house smells of small litter box!
with the small improvements actually a top cage! :)
