The top panel had no hinges for the door so there was no way for the door to attach. Rendering the cage absolutely useless. Called customer service and was told replacement part would take a month to ship, as opposed to three days which took for the cage to get here! I can’t keep my rats in their tiny cage for any longer. They told me I can’t even just return it and get a new one. Now we’re stuck in a limbo and my rats are suffering as a result of their mistake. Horrendous customer service.
