We have 6 ferrets, one is deaf. She is one year old chocolate and we just LOVE her to pieces. Her being deaf is and was NEVER a problem, as she comes when we knock on the floor, she must feel the vibration and know. She watches the others very carefully, and when they come for goodies she is right there with them. We trained her to do tricks, use the liter pan, and do all that the other hearing ferrets do, and she actually listens better and she caught on to some things faster than the others. Some may have problems with their deaf fuzzies, but ours has been a complete blessing, and we are so glad she is apart of our lives. She does know hand signals, the knocking on the floor for when she is hiding, as soon as me knock on the floor she comes out to see what mommy or daddy wants, ALL the time. I hope this helps you, as we just love our deaf ferret as we do all of ours. Bob Taz, Sharkie, Jack, Jill, Bootz, Daisy Lou [Posted in FML issue 3114]
