Hi Bexy This is a very long shot as the Bengal breed of cat has these characteristics but we lost our beloved bengal 'rebel' a number of years ago and never did find out what happened to him but he certainly did all the things that you mentioned. Our other cat, a Maine Coon was delighted when he didn't return, however we were not so enthralled. If you do manage to catch him which would be very difficult indeed, if it is Rebel, he was chipped and would identify him as being ours. Thanks for post as I am sure whoever the owner is would like to see him/her safely returned. All the best Brendan
