Answers:    ok try a water pistol for the cat.

or at hand;s something called Silent Growl which is lion droppings for your garden which is supposed to keep kitty away.

loads of ppl use plastic bottles full of water but i've never specified that to work.

you can get small black metal garden stakes surrounded by the shape of a cat (try a garden centre) which is supposed to put them off.

they don't close to lemon or pine smells so try sprinkling where they regularly stir with some disinfectant.

bury some chicken cable just below the surface of the soil (so you don't own to look at it) so the cat can't have verbs. doesn't work tho if the cat isn't burying it.

you've really got my sympathy here, cos we've get the same problem!
There are garden produces that hold cats off your property, some more obnoxious than others.
