if you try something unique (ie, no shotguns, pellet guns, gopher rtaps,
etc :-) ), i'd like to see your results in a posts here. :-)

Lil, when you get any serious answers I certainly would be interested
also. My mother has a cat that loves to use mine as a litter box also.
So far the only thing that I have found that chases them is I squirt
them with the hose. But that is only a very temporary solution. Also
that only works when I am around to see them in the garden.

if the problem is in a small area, then the 'scarecrow' might work. i'd
try to rig multiple sprinklers to squirt at the cat from all around.
you'll have to fiddle with heights of hoses to keep water from draining,
so it will remain ready in the hoses for each sprinkler.
