I am trying different noises and names to see if he responds to one better than the other, his deafness does not seem to bother him much. Too Tone is finally not hissing at him after the first week so far but Spencer could care a less and boos at him. I am happy I rescued him and paid for him at a none profit shelter, but I hope he will be happy with his little ears. I have to look for him and touch him when he is asleep to say I am home little man.
