How should I care for a rat when it is pregnant? - briefly

Provide a nutrient‑dense diet with increased protein and calcium, a spacious cage equipped with soft bedding for nest building, and limited handling to reduce stress. Monitor weight gain and health closely, seeking veterinary advice if complications arise.

How should I care for a rat when it is pregnant? - in detail

Pregnant rats require specific attention to nutrition, environment, and health monitoring.

A balanced diet enriched with protein and calcium supports fetal development. Offer a high‑quality commercial rat chow as the staple, supplement with fresh vegetables such as broccoli, kale, and carrots. Include a small portion of boiled egg or low‑fat cottage cheese daily for additional protein. Provide a calcium source, for example a mineral block or crushed eggshells, to aid skeletal formation. Ensure constant access to clean water; a water bottle with a sipper prevents contamination.

Housing should be spacious and quiet. A cage of at least 450 cm² floor space per animal reduces stress. Use solid flooring covered with a thick layer of soft bedding (e.g., shredded paper or aspen) to allow nest building. Avoid cedar or pine shavings, which release volatile oils harmful to respiration. Maintain a temperature of 20‑24 °C and a humidity level of 40‑60 %. Keep the cage away from drafts, loud noises, and direct sunlight.

Handling must be gentle and limited. Support the animal’s body with both hands, avoiding sudden movements that could induce uterine contractions. Limit handling sessions to a few minutes, and only when necessary for health checks or cage maintenance.

Health monitoring includes daily observation for signs of distress, such as loss of appetite, lethargy, or abnormal discharge. Weigh the rat every few days to track weight gain; a steady increase of 5‑10 g per week is typical. If any abnormalities appear, consult a veterinarian experienced with rodents promptly.

Nesting material should be provided early in gestation. Offer cotton squares, tissue paper, or commercial nesting pads to encourage nest construction. The mother will arrange the nest before parturition, typically around day 21 of gestation.

During the final days of pregnancy, reduce the frequency of cage cleaning to minimize disturbance. Ensure the nest remains undisturbed and keep the environment stable. After birth, monitor the litter for adequate nursing and maternal care. Do not separate the pups until they are weaned at 3‑4 weeks of age, unless health issues necessitate intervention.

Regular veterinary check‑ups, a nutrient‑dense diet, a calm and spacious habitat, and attentive observation together promote a successful gestation and healthy offspring.
