Can someone please fill me in on the pros & cons of cork flooring? I'm especially looking for info on:

durability (semi-high traffic area for large dogs - will it hold up to their nails?)

cleaning (how do you clean it, and does it stain easily)

installation (easy or difficult, sub floor preparation, how level does the subfloor need to be)

cost

and any other words of wisdom

Thanks for any input you can offer!!!
