We all know our selves when you dont feel well sleep is the best thing, so sleep will be helping frankie,and hearing mums voice and feeling your gentle touch would have been such a tonic to him, this is probably going to sound really daft, especially to the vets/nurses, but could you do a tape recording of your voice talking to frankie and let them play it from time to time, if it works for humans in comas why not our pets while in vets cages, just to let them know your there.......keep us posted on young frankie....in my prayers frankie...love mary xxxxxxx
