I normally practice volleys/half volleys against the back wall of my house. However, recently a cat (or cats) has been pooping in my yard. I have to scoop the poop off everyday before volleying, and I hate doing that. Why can't it poop in it's owners yard :twisted:? anyway, how I can deter the cat(s) from comming into my yard? any natural repellents or 'scarecats' available?
