Thaks again for all your advice unfortunately Sam passed away on 27th June 2010, this is the first time I have been able to log on to pass on this sad news. Thankfully he passed away peacefully in his sleep very unexpectedly, it was a terrible to shock to us all but he is no longer is in pain and at peace. We had Sam cremated and he has a very special place in our sitting room. We have so many fantastic memories and he brought many years of happiness with him. His younger brother Louie is still very much with us and in great health and has been a fantastic source of comfort to us and has hepled us so much.
