Is it worth a trip to the vets? He definatly isnt deaf, but when I open the back door he only knows Im there cos Bunny has heard it and came running out. One day he was asleep so I went to check he was ok. He didnt wake up with me saying his name in a normal voice, only when I said it louder. I thought hed passed away for a moment as none of my Buns sleep around me x
