Long story short, before I moved in my back yard was a main littler box for my neighbor who has i think it was 14 cats. I have attempted planting grazz, soil is almost too acidic (cat pee and urine maybe...) I am fixing that problem. yesterday I found cat poop in my basil pot. A dead bird on the sidewalk in front of my place, I then raked my lawn/dirt and gathered a huge bag of poop. (done this multiple times) What can I do? Anyone know any legal ways of helping me nicley keep the cats away?
I know shooting water helps, but im usually not home from 8am - 7pm... PLEASE HELP

I would speak with the neighbor and ask them nicely to control the problem. If it doesn't stop, you can call animal control and see if they'll come out and trap the cats in your yard, or you can do it yourself.

There are some products you can buy and feed and pet stores which can help repel the cats off of certain areas of your yard.

It is a health hazard to you and it's your right to be protected from bad pet owners such as your neighbors.
