You are recently assigned responsibility for a hamster breeding colony in a biomedical research facility. The number of viable births has decreased over the past 4 months. In addition, there is a high percentage of litter abandonment and cannibalism by the dams. You visit the animal room and observe the following: all hamsters are housed in clear microisolation shoebox cages with ½ inch of corn cob bedding; 700 F room temperature; 45% humidity; 12 air changes per hour; and light timers that are set to deliver 12 hours of light per day. You check a number of the cage cards and discover many of the breeders are 16-18 months of age. Make suggestions to assist the researcher with her hamster breeding colony.</p>
