Our neighbor's cat acts so sweet but then he follows his natural instinct and kills bluejays that have visited our yard for several years and other birds too. First we put our bird bath away but we had crowds of birds hanging around looking at the spot it used to be. So I felt bad and put it back and put a little fence around it and the nearest tree. Well no bird used it with the fence so I put the baths out without the fence. Now I realize birds are being killed in other areas of the yard too. I heard bells around a cat's neck don't work because cats are so stealthy. I realize I can't prevent this but can anyone think of a way to lessen the killings?
