blackthorn rose, why is it different for cats and dogs? If I allowed my dog to go in your garden, or even to roam freely around your garden you'd be justly annoyed, yet cat owners (some) seem to think that they have a god given right to own an animal they can't control.
My garden is cat free. I have never encouraged any of my dogs to chase or attack cats but I expect them to be able to be out on the garden, my garden, without being wound up by cats. happily for my bird population, the local cats agree!
