All of my pets can swim, but the only one who enjoys it is Timber (and Mike, but he's a fish lol). Caleb gets bathed every couple of weeks, and he puts up with it very well, but he would never actually enjoy swimming. Tobias gets bathed once a week and Oliver once a day (my rats), and they HATE it, but they actually tolerate swimming alot more. I guess it's because when I'm bathing them they see it as "power grooming." They are very good little swimmers, but they really don't enjoy it. I like them to swim because it's good exercise.
