I second wellington. I bought a kiddie pool from toys r us for 8 bucks stuck that sucker in the ground and my sully loves it. I keep feesh water out for him but have yet to see him drink...he prob get some during his spa dips as he goes in quite often. I change the water regularly so I can tell if he has gotten in. This way I know he is hydrating. We have awesome weather here in hawaii so I am lucky not to have to worrybtoo much. Will look forward to what others post
