Pregnant hamsters show these traits: nesting, fighting, hoarding food, drinking more, a pear-shaped body and a ‘double-button’ belly. Details: first, a female kept with a male may suddenly attack the male, suggesting pregnancy.
Second, temperament changes with strong territoriality. Third, a swollen body with a small front and large back, the pear shape. The gestation is 18-22 days, with clear signs only in the last week before birth.
