Leave a trail of Top cat food (whiskers or summin like that) That starts in your back garden and leads to your washing machine. Once he has fallen for your expertly masterminded trap, close the washing machine door behind him and turn on for a full spin wash.
That should do the trick
Get a pet greyhound.
cut a fresh lemon in half, squeeze the juice out a bit and then leave the lemon halves by the door. cats hate lemon. simples.
They dont like grapefruit
fill up clear bottles with water and lay them across the lawn, the cat will see its own reflection and scarper.
As a cat lover, i am appauled by this ........
Simple really,dig down about three inches below the surface, lay a metal net in it, cover with bark.
Wire the net up to the mains. Lay in wait. When the offending animal squats down to have a number 1 or 2, shove 240 volts up its jacksy.
befriend, it give it food, stroke it and play with it for a few weeks, then get some of the most lethal hottest chilies you can find cut em up rub them on your finger then when the cat next comes to your garden grab it and stick your finger up it's harris, after that the cat won't come back to your garden!
