Nevada Revised Statutes Title 50. Animals § 574.370. Enclosures generally

(a) Protect the dogs or cats inside from excessive illumination while providing an ample amount of light, by natural or artificial means, or both, of a sufficient distribution and intensity to allow for routine inspection and cleaning.

(b) Provide a sufficient amount of heat when necessary to protect the dogs or cats inside from cold and to maintain their health and comfort. The ambient temperature of an indoor primary enclosure in which one or more cats or dogs are kept must not be allowed to fall below 50 degrees Fahrenheit, unless each cat or dog is acclimated to a lower temperature.

(c) Provide adequate ventilation at all times to maintain the health and comfort of the dogs or cats inside. The system of ventilation must provide fresh air by means of windows, doors, vents or air-conditioning, and be designed to maintain drafts, odors and the condensation of moisture at a minimum. If the ambient temperature reaches 85 degrees Fahrenheit or greater, air-conditioning, exhaust fans and vents, or other auxiliary ventilation must be provided.
