About a month ago I adopted a new kitten. He is about five months old and generally bright. But the little guy refuses to learn his name! He is as likely to respond to "Eli", his name, as he is to respond to anything else. There is nothing wrong with his hearing (he hates the sound of the paper shredder and goes running when he hears it) and he is as bright as any other kitten I have ever had. The little guy just will not learn his name. Is there anything that can be done to help?
