I need a pet gate that is tall enough for a chinchilla not to be able to easily jump over or climb IE preferably vertical bars or fine mesh and that is metal. We've been using a card table to block Loki off from our family room, but obviously that is not ideal because he strongly desires to chew on it. the space is larger than a standard door, and there is no good place to install a real door anyway. Does anyone have any suggestions for what kind of gate can be used, or any other ideas to block off the area during playtime?
