I have a couple of cat pee rings on my lawn and it is terrible. My neighbors have fallen to the same plight. I live in a gated community and a few years ago a couple moved in with cats. They let their cats outside all day and during the night. Now, after reproducing like bunnies we have cats all over our community. For some reason they really like one area of my front porch where there are bushes that have not grown the way I wanted. I had to take 3 little ones to the animal shelter earlier this year. What can I do to ward them off but not hurt them in any way? --peace
