That's right. This cage is too small! I had one like that when I first got my little guy. He was just a baby so it worked for a couple of months or less. It's way too small for 2 chins. Also, the ramps are mesh and if I'm remembering correctly, so are the shelves. Wire flooring/ramps can result in bumble foot (not good), and some wire ramps will allow their little feet to get caught and could end in an amputated foot! The five foot high ferret nation cage isn't that costly and the ramps come with covers. You just need to wrap the two, half shelves with felt so they don't chew the edges. Felt makes am awesome bedding for the chins. they don't chew or ravel it and it cleans Jo so easily
