That was my guess. It is not so hot here, and the directions say to use warm water with the solution. I've never bathed them in cold water, so I wouldn't know, but the limp in warm water makes sense. They are usually pretty tipsy when they get out and need some time under the warm blow dryer to get over the "shock". My Austrolorpe did NOT want the dryer and wanted to air dry. She's the only one thhat got out of the tub running.... and going straight without falling, as well.
