For the past several weeks, we've tried the new (to us) King Bio products on our rats: Aqua Flora Hi Potency 9, Pro biotic Restorer, Constitutional Enhancer and Lung and Bronchial Relief. There has been a gradual reduction in wheezing, except in our 3 year old Zoe. The only thing I hear now is a nasal sound like a stuffy nose and excessive sneezing in a few of the 1-year-old boys. I'm going to take them off of the Lung and Bronchial Relief and put them on something else from King Bio, for nasal or cold symptoms. We give them their supplements in their water when we change it each week. The Rat Retreat, Inc.
