Hey there guys. I have been pondering on how I am going to get this shelving cage idea done so I can move my room around easier and get it cleaned. But I am having issues with the money it takes for the shelving unit. My question is... will these grids..held together with cableties..work for 4-5 levels..?? I am not real keen on it unless they will in fact hold..because if they will..well..I am going to save me some money. I know they are strong enough support wise for multi level cages but I'm talking about actual full cages with bedding and coroplast too..plus 2 pigs per level...and all the extras.. Hmmm.. I am open to anyone's ideas Thanks
