How to keep cats off vegetable patch> Ideas please?

Samuri’s suggestion wins, really lol.

An update – cat came back in the dark and has dug up the exsisting parsnips, some carrots are dug up too. I’m guessing she’s after frogs because I’ve found 2 dead close to the scene of the crime.

As a cat lover I’m not in anyway willing to hurt the animal, so have gone for the bottle of water advice and a neighbour has lent me a gun type thing that makes a very loud noise. Little does he know this will be going onto my handlebars shortly 🙂
