What to use for 2nd level?

Re: What to use for 2nd level?

I've just used more cubes for a second level. My cage is 4 cubes by 3 cubes with a 1 cube by 3 cube second level. The floor is coroplast cut to fit and held on by zip ties. I use newspaper as bedding because the pigs would skid over the edge if I used shavings!

Underneath the cubes is a piece of wood that acts as extra support for the second level.
