First off let me state it is wrong to harm an animal in this fashion. Unacceptable. However, having been on the other side of the fence for every cat that loves you, that cat hates someone else. I love cats, but when I have a dozen strays that peform their duty in my garden they have to go. They also ruined my neighbors porch swing from urinating on it. I humanely trap them and survey the neighbors before turning them over to the SPCA. Please if you love your animals keep them in your yard.
