Sec. 3.2  Indoor housing facilities.

    (a) Heating, cooling, and temperature. Indoor housing facilities for 
dogs and cats must be sufficiently heated and cooled when necessary to 
protect the dogs and cats from temperature or humidity extremes and to 
provide for their health and well-being. When dogs

or cats are present, the ambient temperature in the facility must not 
fall below 50 [deg]F (10 [deg]C) for dogs and cats not acclimated to 
lower temperatures, for those breeds that cannot tolerate lower 
temperatures without stress or discomfort (such as short-haired breeds), 
and for sick, aged, young, or infirm dogs and cats, except as approved 
by the attending veterinarian. Dry bedding, solid resting boards, or 
other methods of conserving body heat must be provided when temperatures 
are below 50 [deg]F (10 [deg]C). The ambient temperature must not fall 
below 45 [deg]F (7.2 [deg]C) for more than 4 consecutive hours when dogs 
or cats are present, and must not rise above 85 [deg]F (29.5 [deg]C) for 
more than 4 consecutive hours when dogs or cats are present. The 
preceding requirements are in addition to, not in place of, all other 
requirements pertaining to climatic conditions in parts 2 and 3 of this 
chapter.
    (b) Ventilation. Indoor housing facilities for dogs and cats must be 
sufficiently ventilated at all times when dogs or cats are present to 
provide for their health and well-being, and to minimize odors, drafts, 
ammonia levels, and moisture condensation. Ventilation must be provided 
by windows, vents, fans, or air conditioning. Auxiliary ventilation, 
such as fans, blowers, or air conditioning must be provided when the 
ambient temperature is 85 [deg]F (29.5 [deg]C) or higher. The relative 
humidity must be maintained at a level that ensures the health and well-
being of the dogs or cats housed therein, in accordance with the 
directions of the attending veterinarian and generally accepted 
professional and husbandry practices.
    (c) Lighting. Indoor housing facilities for dogs and cats must be 
lighted well enough to permit routine inspection and cleaning of the 
facility, and observation of the dogs and cats. Animal areas must be 
provided a regular diurnal lighting cycle of either natural or 
artificial light. Lighting must be uniformly diffused throughout animal 
facilities and provide sufficient illumination to aid in maintaining 
good housekeeping practices, adequate cleaning, adequate inspection of 
animals, and for the well-being of the animals. Primary enclosures must 
be placed so as to protect the dogs and cats from excessive light.
    (d) Interior surfaces. The floors and walls of indoor housing 
facilities, and any other surfaces in contact with the animals, must be 
impervious to moisture. The ceilings of indoor housing facilities must 
be impervious to moisture or be replaceable (e.g., a suspended ceiling 
with replaceable panels).
