This upcoming week I will start my building on my cavy cage. I plan it to be 2x5 for my two cavies, possibly an eventual third. I would like my current marchiaro tommy k 102 cage to somehow attach to it through a ramp. What materials would you recommend for both the ramp and attaching the ramp to the marchiaro cage door?
If that's impossible to do
how would I attach like a 2x2 loft uptop the C&C cage and with what materials?
