Indoor run ideas

[Chrissy24]

As title really. I want to create an indoor run space for them to stretch their legs a bit. What's best to use? Is their anything foldable?

My boys live out in my shed but when they come indoors their temporary cage is c&c grids cable tied together (all except the end two grids). They concertina up for very easy storage. I simply lay down a plastic sheet on the carpet, unfold the grids and pop a few connectors on and the cage is ready to go! The benefit of this is you can add as many grids as you like for the space you have available
