Thanks. I had some plastic chicken wire I put up fencing in the garden when I first planted last spring, to give everything a chance to grow w/out the kitties tearing it up. I still have some & can try that, but have solar lights/ statue etc.. in the area, I would have to work around. She has even pooped ON my little border fence in front of the garden before! As far as the yard, she just pooped right in the middle of it. Didn't even try to cover it up! She is still a little feral. She is mostly outside. (She wouldn't even use a litter box.)
I didn't know if lemon, or other citrus peels would work? Then I could just scatter them around.
Thanks for your suggestion.
