we had central heating at our last house, and i used to keep it set on 23 degree C (73.4 F). one of my ferret's got very lethargic one day, i figured because the temp was too high. i took him outside where it was cooler, and he recovered. we turned it down to around 20 C (68 F) and he was fine from then on. shona [Posted in FML issue 4129]
