Build the Cage
Any indoor cage becomes unusable in August without air moving through it, and it is the first complaint hosts hear from guests. Drum fans are the cheap, loud, effective option for a single tunnel; misting fans add real cooling in dry heat; HVLS ceiling fans move air across a whole facility floor quietly enough to coach over. Size to the square footage rather than the number of cages.
