I have finished my design of the cage and have ordered the cage to go inside the structure I’m going to make. I have challenged my self because I don’t really build many things for animals, but I really think that the Guineapigs will love it .I have faced some challengers with the design since when you move it and leave it where you want, it’s wheels will keep it of the grass. so I fixed this problem by making the wheels lift up and down. So when you move it you un clip it and then once you are done you put the wheels back up on the clip. The next thing I will do will be the structure and cutting out the bottom of the cage so the grass can grow through and they can eat it.
