What does a rat's cold look like? - briefly

A rat with a cold typically shows nasal discharge, sneezing, and watery eyes, while its fur may appear dull and it may exhibit reduced activity and a slight loss of appetite. Respiratory sounds may become audible, and the animal often breathes more rapidly than normal.

What does a rat's cold look like? - in detail

A rat suffering from an upper‑respiratory infection displays a set of observable changes. Nasal discharge is the most immediate sign; the fluid may be clear at first and become thicker, yellowish, or greenish as the condition progresses. The animal’s whiskers often appear damp, and the fur around the muzzle may be matted with secretions.

Respiratory effort increases. Breathing becomes audible, with a wheezing or rattling sound that can be heard when the rat is at rest. The chest may lift more rapidly than normal, and the abdomen may show exaggerated movement during inhalation. In severe cases, the rat may adopt a hunched posture to ease airflow.

Behavioral alterations accompany the physical symptoms. The rodent typically reduces activity, spends more time in the nest, and shows a diminished appetite. Water consumption may rise if the nasal passages are congested, and the rat may lick its snout repeatedly to clear blockage.

Additional indicators include:

  • Redness or swelling of the nasal passages and surrounding skin.
  • Ocular discharge, often accompanying nasal exudate.
  • A drop in body temperature detectable by a rectal thermometer; hypothermia is common in small mammals with infections.
  • Weight loss over several days, measurable by regular weighing.

Laboratory evaluation may reveal elevated white‑blood‑cell counts and the presence of bacterial colonies in nasal swabs. Radiographs can show fluid accumulation in the sinus cavities and, in advanced cases, pneumonia in the lung fields.

Prompt veterinary assessment is essential because untreated respiratory disease can progress to systemic infection, organ failure, or death. Treatment typically involves antimicrobial therapy, supportive hydration, and environmental modifications such as increased humidity and reduced stressors. Monitoring the described signs daily allows for early intervention and improves the likelihood of recovery.
