Sherri, Please forgive the tardiness of my response, I'll still 10 FML's behind. I regularly take my ferrets in the pool with me and I haven't seen any problems from the chlorine in the pool. I have always been more concerned with them getting water in their ears but they do very well at keeping their head out of the water so that hasn't been a problem either. Some like it, some would rather skip the swim and explore the gardens by the pool. ;) They seem to like the spa in the winter better, probably because it's kept at such a high temperature. It's adorable to watch and I highly recommend it for ferrets that don't hate water, but I would advise always swimming with them. Hope this helps! Susie [Posted in FML issue 2009]
