cat poo

Coleus canina, otherwise known as the 'Scaredycat plant'. Available on ebay and all good mail order plant distributors. It has a pong, undetectable to humans, that cats can't stand.

Push some very spiky twigs into the soil (Pyracantha is good, or holly) or invest in an electronic cat-scarer.

Do they work, the electronic scarers, I mean? Have you tried one volunteer?

I keep them off my raised bed and off gravel very effectively with black plastic mesh.

invest in a shotgun end of problem period

I found the ideal solution was good old-fashioned 'mothballs'...... you can still buy them at Wilkinsons. Or, a while ago B&Q were selling 'Zoo Poo' which was dried (and not smelly) big cat poo; little cats daren't argue with that!

No, I haven't actually tried one but have heard that they are quite good. A bit pricey though!
