My boys finally got to explore their new cage today. We had to cover the barred ledges with linoleum to protect their feet and also to make it more comfortable to walk on for them. The linoleum is also easy to clean. I fastened it to the floors with cable ties (snipping the ends off so they cannot be chewed). The cage also came with wire ladders that I have turned into sturdy ramps using carpet. I simply glued the carpet to the ladders.
After lining the main floors with our paper based substrate and decorating with a hammock and tent we let them into the cage for the first time. Here are the pictures.
