There is very useful information at this website.

I am interested in knowing the source of the recommended space dimensions for the cage and a source that states it can't be split over two levels. I agree with many of the posts at this site, berating the very small cages. Those should never be sold to house any small animals. However, if the original poster is referring to the cage in the link, that is definitely a suitable home for a dwarf hamster.

I own that Ferplast cage, 3 smaller cages and a large 4' x 3' rabbit cage. What cage does my dwarf hamster prefer? The smallest cage. It bothers ME so I have the little cage open in the rabbit cage. (The bottom tray of the rabbit cage is high so she can't escape.) Little Zoey goes back and forth between the two once in a while, but spends almost all her time in the little cage.

I am genuinely interested in a credible source, regarding the cage dimensions and not having them split over two levels.

Thank you,
Cotton
