Sec. 3.26  Facilities, indoor.

    (a) Heating. Indoor housing facilities for guinea pigs or hamsters 
shall be sufficiently heated when necessary to protect the animals from 
the cold, and to provide for their health and comfort. The ambient 
temperature shall not be allowed to fall below 60 [deg]F. nor to exceed 
85 [deg]F.
    (b) Ventilation. Indoor housing facilities for guinea pigs or 
hamsters shall be adequately ventilated to provide for the health and 
comfort of the animals at all times. Such facilities shall be provided 
with fresh air either by means of windows, doors, vents, or air 
conditioning, and shall be ventilated so as to minimize drafts, odors, 
and moisture condensation. The ambient temperature shall not be allowed 
to rise above 85 [deg]F.
    (c) Lighting. Indoor housing facilities for guinea pigs or hamsters 
shall have ample light, by natural or artificial means, or both, of good 
quality and well distributed. Such lighting shall provide uniformly 
distributed illumination of sufficient light intensity to permit routine 
inspection and cleaning during the entire working period. Primary 
enclosures shall be so placed as to protect the guinea pigs or hamsters 
from excessive illumination.
    (d) Interior surfaces. The interior building surfaces of indoor 
housing facilities shall be constructed and maintained so that they are 
substantially impervious to moisture and may be readily sanitized.
