The neighbor told my son, not myself nor my spouse, that our cats ate 10 of his goldfish from his pond, and he wants us to keep the cats out of his yard. And he would hate for something to happen to our cats. He was the rocketscientist who built the pond, all the while the cat was up in the tree watching him, and he pet her and visited with her. Now common sense dictates if you don't want a cat in your yard shoo it away with water or whatever. We don't have leash laws for cats and I don't know what to do, it's over 100 degrees (great temps for pond fish). I'm sorry about his fish, and I'll buy him some more, but I'm not going to lock up my cats. And for his sake I hope nothing happens to my cats either, since he has such an emotional attatchment to his fish. Am I crazy?
