How long do Dumbo rats grow? - briefly
Adult Dumbo rats typically attain a body length of 12–15 cm (approximately 5–6 inches), with the tail extending an additional 5–8 cm. Growth stabilizes by 4–5 months of age.
How long do Dumbo rats grow? - in detail
Dumbo rats reach a mature body length of approximately 7 to 9 inches (18–23 cm) measured from nose to the base of the tail. The tail itself adds another 4 to 6 inches (10–15 cm), giving a total span of 11 to 15 inches (28–38 cm) in fully grown individuals.
Growth proceeds in three recognizable phases. Newborn pups measure about 2 inches (5 cm) and weigh 5–7 g. During the first three weeks they gain roughly 0.5 inch (1.3 cm) per week and double their birth weight. By the fourth week the average length approaches 4 inches (10 cm) and weight rises to 30–40 g. Between weeks five and eight the rate slows to 0.2–0.3 inch (0.5–0.8 cm) per week, with weight reaching 80–120 g. Full size is typically achieved at 4–5 months of age; some individuals continue to fill out until six months.
Sexual dimorphism influences final dimensions. Males generally add 0.5–1 inch (1.3–2.5 cm) to body length and 20–30 g to weight compared with females. Genetic line, diet quality, and health status also affect growth; high‑protein feed and regular veterinary care promote optimal development, while chronic illness or malnutrition can stall progress.
In summary, a Dumbo rat’s adult body length ranges from 7 to 9 inches, with total length including the tail reaching up to 15 inches. Full growth is completed by five months, with minor variations due to sex and environmental factors.
