Need Help!!

We have been refurbishing our (huge) garden over the last two years. We have got to the end of the garden and had a patio put down with a begoda above it. There is a waist high embankment at the very back which smells strongly of cat urine (which is not very nice as its an eating area!)

We have two cats - so its partly them - and the strays seem to be using that area too. We plan to add plants but before we do we need to know how to get rid of the awful smell...?!

Someone advised cayenne pepper but it burns cats noses and we don't want to hurt them - just to get rid of the smell and to deter them. Should I be putting orange peel over the area? Its a fairly large area.... maybe buy some orange oil?

Any help much appreciated
