Detailed Pregnancy Signs and Care Guide for Chinese Dwarf Hamsters
Compiled from multiple authoritative sources
I. Identifying Pregnancy Signs
1. Physical Changes
Around 10 days after conception, the abdomen will visibly swell—changing from a teardrop shape to a pear shape. When gently touched, hard lumps (the developing fetuses) can be felt.
Weight increases steadily, with a daily gain of approximately 2 grams (normal adult weight ranges from 35–50 grams).
2. Physiological Markers
The nipples become red, swollen, and prominent (1–2 mm in diameter), with sparse fur around them, resembling small cherries.
The gestation period lasts about 16–22 days, slightly longer than that of Syrian Hamsters (golden hamsters).
3. Behavioral Abnormalities
Nest-building behavior intensifies: the hamster will frantically tear up cotton, wood shavings, or other materials to build a nest.
Aggression increases significantly. If housed with other hamsters, separate them immediately.
II. Key Scientific Care Tips
1. Environment Adjustments
Provide a hidden nesting area (e.g., a small wooden house filled with dust-free paper bedding).
Remove exercise wheels and keep the environment dark and quiet to avoid disturbing the pregnant hamster.
2. Diet Management
Increase high-protein foods in the diet, such as mealworms and boiled egg (chopped into small pieces).
Supplement with calcium-rich vegetables like broccoli (washed and dried thoroughly before feeding).
3. Important Precautions
Avoid frequent handling or touching the pregnant hamster, as stress may cause her to abandon or harm her pups after birth.
If vaginal bleeding or refusal to eat is observed, seek veterinary care for exotic pets immediately.
III. Preparation for Delivery
Within 48 hours before giving birth, the hamster will develop a "penguin gait"—walking with its hind legs spread apart.
Do not clean the nest for the first two weeks after the pups are born, as this may disrupt nursing.
Tip: Chinese Dwarf Hamsters show obvious behavioral changes during pregnancy. It is recommended to use a combination of weight monitoring and nipple observation to confirm pregnancy. If you are unsure, consult a veterinarian specializing in exotic pets.
