Study Notes
Hamster Gestation and Anatomy
- Gestation period for hamsters is 16 days.
- Hamsters have a distinctly compartmentalized stomach, differentiating their digestive system.
- Brown adipose tissue is found between the scapulae of hamsters.
Hibernation and Behavior
- Hibernation leads to decreased body temperature, slowed respiration, and increased sensitivity to touch, but heart rate does not increase.
- Cannibalism and litter abandonment commonly occur during a hamster's first pregnancy.
Hamster Species
- The Chinese hamster is the smallest variety, recognized by its gray-brown coloration and dark dorsal stripe.
- The Syrian hamster’s scientific name is Mesocricetus auratus.
Hamster Health and Diseases
- Proliferative ileitis, known as "wet tail," is the most common spontaneous disease among hamsters.
- Antibiotic-associated enterocolitis can develop due to antibiotics disrupting normal intestinal microbial flora.
- Zoonotic concerns exist with conditions like lymphocytic choriomeningitis and Campylobacter, but Syphacia obvelata is not zoonotic.

- Female hamsters can be mated successfully on the evening of the 3rd day after observing postovulatory discharge.
- Lordosis is the breeding position assumed by female hamsters.
Genetic and Physiological Terms
- Cytogenetics is the study of chromosome structure and function.
- Polychromasia refers to the tendency of hamster red blood cells to have varying affinities for stains.
- Amyloidosis involves excessive deposition of protein fibrils in organs, notably the liver, kidney, and spleen.
- Hamster pups are hairless at birth, and their incisors are fully erupted from the time of birth. Eyes open at 5 days, contradicting earlier assumptions.
