Actograms of domestic cats were obtained in two settings, in a large animal colony where there were many cats and people, and in isolation in sound-attenuating rooms. For the four cats that were studied in individual isolation, freeruns were obtained in constant dark, and then recordings of sounds from the animal colony were presented once a day at the same time for eight hours. Entrainment by the colony sounds was demonstrated in three of the four cats. The cats in the main colony exhibited a nocturnal pattern of entrainment to the LD cycles. The humans, present during the L phase, induced a prominent band of activity on the actogram. Because both LD cycles and laboratory routines have separate and independent capabilities of entraining the circadian system, Zeitgebers for the cat may be typically complex and diverse so that all temporal aspects of the environment are exploited. |
