I bought several plants and they had no effect. I also used 'Lions Roar' which was also no use.
I invested in an electric cat scarer (about �26) and have had no cats in my garden since.
My sister has a neighbour with 11 cats! she bought a similar scarer which can work with a battery or electric and no cats come into her garden now.
The battery however needs replacing so the elctric one is better. Well worth the money as you eventually spend quite a bit buying things that don't work.

hi otchen - which elec' cat scarer is it, i have tried allsorts from tea bags soaked in all manner of substances to using my own urine (no i don't do it in garden - i collect in an old plastic jug) i think this may have turned some cats on, by the way i am male. (last time i looked)
