I hate to tell this but we have neighbors that have numerous cats and they destroyed our flower beds, porch furniture cusions, in our garage on our cars when the door was open. We spoke to the cat owners many times and it did no good. DH bought a live trap and when he caught one we would take it to the SPCA and they would contact the owner and they would pay a fine and get the cat back. A few times of doing this they got the message.
