Can anybody help me out there? I have a nice, green, healthy lawn and
take great pride in it, but every cat, including my own now, is using
it as a toilet. Now I have read about pellets and electronic devices
but I wonder if anyone out there has used an effective deterrent.

I find it helps to keep the lawn short. I have found that cats only tend to
use it as kitty litter when its over 1" high.
