I have been following this thread, too, and I am incensed with the obvious lack of caring that the management of the hotel has expressed. I also posted my opinion on their fb page and let it fly!
This incident really has opened my eyes that you really cannot trust ANYONE with your kids ( fur or otherwise!) like you can. Never take for granted that your pet will be safe in it's room if you're travelling. If I ever have to take my boys with me somewhere, I'll have a kennel large enough for both of them and will have it padlocked and chained to the furniture, lol!
To the OP--my thoughts and prayers are with you, and Benji, and will do everything I can to help get him back home to you and your family!
