Curt is on 1 unit of Pro Zinc every 12 hours. Well this morning I slept thru the alarm clock and his shot was a little over an hour late. Tonight at +10 he is only at 177. Usually at that time he is approaching 300 or higher. Should I reduce to .75 or maybe no shot at all? Im actually about to leave for the evening and would hate to come home to a hypoing cat. Whats the safe thing to do?
