I’m just thinking as he knows his dog has actually killed a cat, only saying what I would do as I couldn’t deal with what happened, I agree, he has no responsibility to do that.I agree with almost everything you said here. Apart from the part highlighted. I think the neighbour is a bleep and a horrible person by the sounds of it. But why should they have to cat proof their garden? It's not his cat! It's as much instinct for that greyhound to kill that cat as it is for an outdoor cat to roam into other people's gardens. I used to live beside a family with two cats who always came into my garden to try wind up my German Shepard. They would sit on top of the shed where he couldn't get them and hiss at him. Now if my next door neighbour asked or tried to insinuate I need to cat proof MY garden I would have told him where to go...
Life span of outdoor cats is 2/5 yrs, I think this is due to accidents. Didn’t know that. Scary.
