How do male pet rats look? - briefly
Male pet rats typically have a sleek, elongated body, short hair, and a pointed snout; their fur colors range from black, brown, and white to mixed patterns, and they often display a slightly larger, more pronounced genital area than females. They possess a long, hairless tail and sharp, dexterous front paws suited for climbing and handling objects.
How do male pet rats look? - in detail
Male house rats typically measure 20–25 cm from nose to the base of the tail, with a tail length of 15–20 cm. Their bodies are compact, with a rounded torso, short limbs, and a slightly arched back when standing.
Fur color ranges widely. Common shades include:
- Black: solid, glossy coat.
- Brown: ranging from light beige to deep chocolate.
- White: pure or with pigmented patches.
- Agouti: banded hairs producing a speckled appearance.
- Hooded: dark mask over the head with a lighter body.
Pattern variations may combine these base colors, producing brindle, sable, or merle effects. Fur texture is smooth to slightly coarse, depending on the breed line.
Sexual dimorphism is subtle but observable. Males possess a visible anogenital distance that is longer than in females, and a small, rounded scrotal sac located beneath the tail base. The preputial gland, a small raised area near the vent, can be more pronounced in intact individuals. Tail hair is typically sparser, allowing the underlying pink skin to show.
Visual signs of health include bright eyes without discharge, a clean, unbroken coat, and a steady body weight. Any loss of fur, lesions, or swelling around the genital region warrants veterinary assessment.
