Jan says the way to do it is to put it around the perimeter of your garden or around the patch of garden to be shielded. She's done it herself-- (in Bradford on Avon)-- and it works. (She had over a dozen cats living in the house 2 doors over ---and she had tried every other so-called deterrent). She says this idea was being pushed by gardening programs, wildlife experts, and zoos. Bristol Zoo kept running out.

There was a waiting list for it.

She says Alan Titmarsh announced one spring that one of the local zoos had run out---and at the zoo there was a sign saying "No Tiger Poo Available".
