First2fish some of the older cats do stress out easily in the heat and can die if not taken care of. I'm not a fan of any pay lake and I would suggest save your money and by a big cooler of your favorite beverage and head to the river. If you are catch and release any way it won't matter.And believe me some of those lakes that say all there cats are grain fed from such and such..well I fish such and such river and have stocked a few of those so called lakes good luck Chuck
