I have 2 yr old cat which was very well and very happy but unfortunately I have found my cat dead lying on its side; it was slightly under my neighbours’ car on his drive way which had not moved at all today. It was absolutely stiff and its eyes were wide open, it did not show any signs of harm to it and had tiny traces of fur in its mouth. It was generally a very healthy cat but it may have had a cold lately as it had the odd sneeze on occasions. I wonder if you can tell me what had led to its death. It had been missing from the house overnight
