I thought this looked perfect for my older, arthritic piggies. The lower ramps gave me less concern for my 7-year old who doesnt know he has arthritis. However, he was really scared of the open ledge and wouldnt do more than test out the ramp for a few steps. I used zip ties to attach the decorative dome grid to the base of the ramp and the top cover, making a little arched side rail. He LOVES it now! It's where he zooms when he gets a cookie. His girlfriend (they are both spayed/neutered) tends not to go up there, so its his & base They both love the dark hiding spot underneath the perch for sleeping, and Ive put a heating pad under their fleece in that area, making it their favorite spot in the whole cage. My C&C was already put together with zip ties instead of the plastic connectors, so the perch is a little bit wobbly, even after having secured it with a ton of ties. Im really glad to have the extra support/security of the dome grid to prevent an accident off the ledge.
