Another Gravesend 'big cat' sighting ?

From female witness: 'On Saturday 12th Feb. 8 of us were in Mill wood. We had walked from Cobham, past the Mausoleum, and stopped on the ridge to look across in the direction of Upper Bush. We could see across the valley. In a field, high up on the other side of the valley. We could see, what looked like a large black animal moving across the field. It was alone and moving slowly. We all stared at it, trying to make out what it was. It was low to the ground and seemed to move smoothly. We were trying to work out it's size. It disappeared into the woods. Shortly after, a person came out of the woods, lower down the hillside with 2 dogs. We could then tell that the animal was about the size of a big cat: the length of an horizontal person. We could hardly see the dogs, they were much smaller than the animal we saw.'
