So I got the motion sensor sprinkler and I works like a charm! No poop in my yard! Everytime I hear it I can't help but chuckle to myself knowing that some machine gun pooping cat just tasted justice. This has got to be the best $60 I've ever spent and I think I might get another one for the general back alley behind my house to keep them from spraying (it stinks so bad back there).

I've posted on here about my problems with cat litter in my backyard, which I assumed was from a feral or my neighbor's cat. I come home tonight to discover cat litter in my yard that is covered in kitty litter sand, so it was thrown over into my yard.

I currently am using a cat detterent spray, pepper flakes and mothballs to keep the cats out of the yard, so I'm pretty sure it's being thrown into my yard.

Any suggestions on steps to take? I'm assuming SPCA, but now I'm considering the police because it is considered trespassing

That's nasty - so cat poop is being thrown into your yard? Do you know the neighbors who are doing it? That has GOT to stop! Nasty.

As an aside, I have started helping out just a little with the Trap-Spay-Return thing on my block and it is really satisfying to be doing something good that also makes the cat pee smell much less nasty and stops the spraying!

So someone is tossing used cat litter in your yard???? What side is it coming from?

I believe it's coming from the people who's back area butts up to mine but they face a different street, I believe...
Not definate...

A limited understanding of anatomy makes this obvious

If you have a cinderblock wall or something similar, try lining the top with chicken wire. This has worked for us; apparently, cats hate walking on the stuff. We bought a roll of chicken wire, trimmed to the width of the back patio wall, and placed securely. In the month or so since, we haven't seen any cats on the wall. We're still working on sealing off the rest of the patio, as are our next door neighbors, since they're also not exactly aficionados of cats***, and we share a common wall (it helps to have a concerted effort).

Unforunately, the guy who feeds them is in fact an aficionado of cat***t, and doesn't look like he'll be giving up his hobby any time soon.

I'd also thought about the motion detector sprinkler, and although that sounds like a lot of fun, it isn't practical for our yard.
