Thank you for all your kind thoughts and replies. It is really helpful to read them. We are finding the house very quiet at the moment, and are still expecting to hear the padding of paws, to feel the nudging of Frankie's nose for a cuddle...yes, and even hear the slurping up of water and all the other habits of an old boy! You might be interested to hear that Frankie did not have a heart murmur, though he lost most of his hearing and his sight in the last year. He loved his food until the end! Our girls are very sad but coping really well. Thank you again, Susanne xx
