Just a basic cage with a loft. The ramp is 18" of Oak that my boyfriend and I covered with the softer side of velcro. There are three pieces of it on there that are about 2 inches wide and they run the length of the wood.
Very nice. You should provide loose hay or hay in a hayrack, though. The Rollin' The Hay wheel makes it tough to get the hay out, and hay is an essential part of a cavie's diet.
My Little Pig is very adept at getting hay out of that thing! He somehow manages to get HUGE chunks out at a time... Thank you for the suggestion though!
