Hey I know you posted this 2 weeks ago I loved your video your cage is awesome this helped me a lot I’m looking into building mine like this but also a tip to help with the weight of the top cage you can add 1 or 2 wooden dial rods the long wooden sticks you can get them at basically any craft store or Home Depot or Lowe’s for cheap but it should also help with the weight of the top cage just cut them to the length of the cage and slide them in right underneath the bottom floor support grids if you get what I’m saying 👍🏼
