Hi Everyone.I am hoping someone may have some ideas on how to add traction to the plastic ramps,and especially tunnels,in the 4 story super pet cage.My older bottom heavy ferret has difficulty hauling his butt up the steep slippery ramps,and finds the little tunnel near impossible. Also,does anyone know if replacement ramps can be purchased and where? It would maybe be easier to change the tunnel to a ramp .I think I may have seen this topic on here before,but can't remember.
