How does a three-month-old domestic rat look? - briefly
At three months, a pet rat is roughly 20–25 cm long including its tail, with a smooth coat that may be white, brown, black, or mixed, a pointed snout, small rounded ears, and a tapered tail about the same length as its body. Its eyes are dark and its whiskers are prominent, giving it a compact, agile appearance.
How does a three-month-old domestic rat look? - in detail
A three‑month‑old pet rat is nearing full adult size but still displays juvenile characteristics. The body length, measured from nose to the base of the tail, typically ranges from 12 to 15 cm (4.7–5.9 in). The tail adds an additional 15–20 cm (5.9–7.9 in), nearly matching the body in length and remaining flexible and hair‑free. Overall weight falls between 120 and 180 g (4.2–6.3 oz), with males usually heavier than females.
Fur is dense, short, and glossy, covering the entire dorsal surface. Common coat colors include albino (white with pink eyes), black, brown, agouti, and various patterned combinations such as “hooded” or “piebald.” The ventral side is lighter, often white or pale gray, contrasting with the darker back. Whiskers are long, stiff, and evenly spaced around the snout, providing tactile feedback.
Head features include a rounded skull, large eyes that are bright and alert, and ears that lie flat against the head, covered in fine hair. The nose is pink and moist, and the mouth reveals a set of continuously growing incisors that are visible when the animal gnaws.
Limbs are proportionally short but robust, ending in five toes on each hind foot and four on each forefoot. Digits are equipped with small, sharp claws used for climbing and digging. Musculature is well‑developed, allowing rapid bursts of movement and agile navigation of tunnels.
Reproductive maturity is approaching, especially in males, whose testes become palpable. Females may show early signs of estrus, though full fertility often occurs slightly later. The overall appearance reflects a healthy, active animal ready for adult responsibilities while retaining the softness of a young pet.
