I just checked on the Ferplast website to see if the dimensions were correct in the Amazon link. It says 60 x 36.5 - it's not too bad. It is on the small side for a dwarf hamster but if a smaller cage is preferred the dimensions aren't terrible. 36.5cm is still narrow (but not as narrow as the 35cm Amazon quotes) and approx the same depth as a detolf. Obviously not as long and it does allow for activity. Bigger than a mini duna at least. It's just a shame it's not 40 to 45cm deep then it would be a good small cage.
Generally though it would be considered a bit too small for a dwarf hamster and totally unsuitable for a Syrian hamster.
Had to laugh at the description though! Presumably translated from Italian - a cage with a "high bottom" lol.
