I rescued this kitten from a busy road. He was very sick and nursed him back to health. He is bright eyed and bushy tailed now. I have noticed if clap my hands or call him his ears do not react. I talked to the local vet on the phone and he told me to clean his ears out - which I did, with no improvement. Is there any handicap for him if he is deaf? He is the sweetest little thing. Funny question: Can cats learn sign language?
