[cypher]

The only problem I had with the outside was that it's a bit of a pain getting little seeds & bits of food out of the cracks in the bark! With two hams living their whole lives in one (not at the same time!) I didn't have any problems, I didn't even plastikote inside but I was lucky as both used litter trays from day one, if I was to use one again I'd plastikote inside though.
The only thing I really don't like it is the very small space under the ramp is a good place for nervous new hams to hide where you can't get to them, even though I prefer the German labyrinth houses that was the only fault with this one really, for dwarf hams anyway.
