Critter Space Pods (bonus link because rats LOVE them)
Rope Bridge (I hang the critter space pod in the corner of the cage and angle the rope bridge underneath it, so its easier for them to get in and out of the space pod. also it's nice because if they fall out of the space pod, the rope bridge will catch them)
This is a lot of fun! :)
This is the cheapest thing on any of my wishlists, I like the green one and my old cable broke: http://www.amazon.com/SODIAL-Piece-Charger-Cable-Iphone/dp/B009VYHAGS/ref=wl_it_dp_o_pC_nS_nC?ie=UTF8&colid=3NL5U5G6CIH6L&coliid=I1DRJFAPRFWNHK
Helpful Item: This would be great for my pet rats, they tend to tussle a bit and it'd allow them to have some personal space from each other: http://www.amazon.com/Lixit-Critter-Space-Pod-Large/dp/B002X2NBNQ/ref=wl_it_dp_o_pdT1_nS_nC?ie=UTF8&colid=3GEYT81OU35RQ&coliid=I1LGD2IAHI6O1U
