Just an update, we spoke to the gamekeeper on our estate at the weekend, he asked us if one of our cats was missing, we explained about Lou Lou and he said that he had found a dead cat by the lanes at the edge of the estate, he had put it to the side of the lane but it had gone (probably taken by foxes) he said the cat was black and white, Lou Lou Flump was a dark grey and white tabby but if she was wet she would look black and white, so we cant do anything else than assume it was Lou Lou and we are heartbroken. We live in the middle of 400 acres and there is only three other cats in the area other than ours, one of those is Gerry who is grey and still very much alive, the other is a ginger boy (Ruby Red and PPP's brother who lives at the manor house) and the other is a very petite lady cat who lives with the land owner, again not black and white. So unless it was a cat who had wondered a good few miles it sounds like it may have been Lou Lou Flump. I am so gutted, we live where we live especially for our cats, we often joked that they only thing they would get run over by was a blade of grass or a horse, I feel like I have failed Lou Lou.
