wide shot of cage - Guinea Pig Cages

nice cage and second level may I ask what is the ramp made of and can they go up such a steep ramp

This is an old cage from 2 years ago. The ramp was made from cube that was bent in two spots, creating a flat surface with 2 walls. I put cardboard on the flat part and wraped the cardboard with some trifold cloth diapers that we never used. and then I took some scrap fabric (purple) and tied it around the cloth. this kept the cloth in place and gave them extra grip. They never had a problem with it.

The ramp comes down, flatens and then goes the other way like most staircases.

This is my current cage, which I think improves on previous designs. It is much easier to clean.
