Niteangel Natural Living Tunnel System, Small Animal House https://www.amazon.com/dp/B00OW6ZO9U/ref=cm_sw_r_cp_apa_i_jpFACbCZ0ZTQE

I bought this for my boy Eli for Xmas...he lost his marbles...he loves it soooo much...he has a 20 gal long tank so you can fit the whole thing inside but it doesn't leave room for his wheel. I took the houses apart so each week I change out the houses so they can air out and I gave the connecting tunnel log to his baby brother leif in a separate tank...I first bought Eli this...Niteangel Natural Wooden Hamster Mouse Tunnel Tube Toy Forest Hollow Tree Trunk https://www.amazon.com/dp/B00OW44P56/ref=cm_sw_r_cp_apa_i_4sFACbT7F5QKX
