After reading through everything, think I finally understand the situation. Gotta go w/ Sundari's perspective on this one -- best not to overlegislate, and let people think and research it out on their own. Suspect vast majority of people will do a LOT better than the 1 sq. ft. min., while tiny minority of cruelest and/or most clueless owners generally won't follow the law anyways, no matter how you word it.
