I am taking care of a kitty who is deaf and going to deliver any time. She was found as a stray and was unfortunately too far along to get spayed. This will be her last litter. Does anyone have experience with deaf mothers? I am aware some of her babies will be at a high risk of also being deaf. Are there any things I should watch for since she can't hear her babies crying? Any other advice from anyone who has been in this situation in the past?
