Number of things work. Orange peel seems to put them off, as does lion
dung (available in dried form in the UK from most garden centres).
There are also many plants that a cat doesn't seem to like the smell
of but I've lost the list I had so I will leave that up to some other
person to post.

 Hi,

 Can any body tell me how I can prevent my neighbour's cats pooing in my
 front garden, they always do it at the same place. I am so sick of it,
 though I am an animal lover.
