Silent Roar Lion Manure sort of works. It's power station clinker impreganted with lion p*ss, or something that smells like it. Or water with washing up liquid in it puts them off. They generally don't like a soaking very much, and it tastes awful when they lick their fur, or at least Fairy Liquid does. Try some on your tongue to see what it tastes like!! Another thing is a PIR-driven soaker. Connects to the garden hose tap, but triggered by anything that normally triggers PIR, including people!
Someone tried to sell some to me..........One question, how does a Cat or any other animal, born and bred in Yorkshire, recognise Lion **** smell.
