Bought this to stop the neighbouring cats from walking across a wall at the foot of our garden. I like cats, but my dog gets a little rabid at the sight of them and barks (which sends my neighbour into a spin). We have covered the top of the wall in this lion dung product and, if anything, the local cats are spending MORE time on the wall and really savouring the whiff of leonine poo! I guess our local cats are hard core. Don't bother buying this unless the cats you are trying to deter are pathetic little townie types who have never been on safari.
