Plenty of space. However, my hamster can't climb the ladders, without sliding. There are small gaps at the bottom pull out pan, which could injure my pet. The floors should be full floors and not half. Pet could fall through opening. It needs a door at the top of cage, for easy access of cleaning or to retrieve pet. Bottom pan should be deeper for burrowing. Cage should come with water bottle and food dish at the very least. I had to put my hamster back in her old cage, until I modify this new one.  I will place books under pan, not to have gaps. Self Adhesive Felt, will go on the ladders for easy climbing. 20 inch long hammocks to stretch across openings, in the event my pet should fall. Delivery was speedy. Assembly was difficult. Parts did not have sticky ABC labels for easy understanding. If you buy this product, be sure to modify first for your pets safety.
