oh i hate habitrail ovos! i just do not see the point in them
You can't fit any toys in them, there so expensive and just not worth it.
Sorry i don't mean to start a rant here
But i do really think they are just aimed at children who don't know any better.
I'm all for colourful nice compartment designs (i have rotastak myself)
But only when you truly respect the room and care a hamster needs.
(none of this is directed at you A7X4 btw, was just putting my point across)
