I’m pretty sure that one of my bunnies is deaf. If he is faced to me when I walk toward him, he will come running, hoping I have a treat for him, but if his back is turned to me when I walk toward him, he doesn’t respond at all – even if I call his name or make sounds to attract his attention. He is a very sound sleeper, and I sometimes have to shake him awake when I have food for him. He seems very happy, though, so I guess it doesn’t bother him. He and his companion spend a lot of time out on our screen porch and I hate that he can’t hear all of the birds tweeting and singing in the nearby trees.
When we first adopted Bosco a few years ago, he had airplane ears, but with time, he looks more like a lop. I believe that he had hearing at first because he didn’t give me a reason to think he was deaf then. I remember one time when my husband was in the hall and Bosco was laying in one of his favorite spots in the living room – under the coffee table. My husband said Bosco’s name loudly, and he popped up in the air. It wasn’t until the last year or so that I began to suspect he was deaf.
