My cat Stinky is all black. He turned 8 years old on January 16th, 2009 - and he doesn't listen. This may mean he may be deaf -- but then on the other hand he may just be stubborn. When I pet his head, he winces away and runs and lowers his ears down. I'm not too experienced with disabilities in cats or other animals..so what does this mean..does deafness affect and hurt??
