I know that several times people have given web sites and what not for these conversions. We recently bought one, because it was the largest cage that fit through the door to the ferret room. We purchased two extra shelves, and plan to add more hammocks when it gets here. Any other ideas would be appreciated. Thanks, Kim and the Zoo Crew in Reno Norman the 7 month old, 130 pound mastiff. "Huh?" Sherman the 10 month old basset "I am so stubborn!" And Bullet, Murphy, Cassie, Dunkin, Chester, Benjamin and Daniel....the 7 most spoiled wezls. [Posted in FML issue 3600]
