There be Dragons

The other evening we sat in the lounge with the patio doors open . Instrolls a lovely ginger cat(which Ive named Tom Sidney,for some reason)we've never seen him before and we have no near neighbours. Bold as brass he stands there while my daughter fed it some ham. He had a stroll in and out a couple of times. Eventually when we shut the doors he was pawing at the glass to get back in! My daughter looked up the postcode that was on his collar,and he comes from about 1/2 mile away.Havent seen him since!
