What should you do if a rat overheats in the sun? - in detail
If a small rodent becomes overheated while exposed to direct sunlight, immediate action is required to prevent heat‑related injury or death.

Remove the animal from the heat source. Gently lift the rat and place it in a shaded, well‑ventilated area away from direct rays. Use a towel or gloved hand to avoid burns to your own skin.

Lower body temperature gradually.

Apply a cool, damp cloth to the neck, back, and limbs. Do not use ice or freezing water, which can cause shock.
Offer a shallow dish of fresh, room‑temperature water for drinking. Do not force the rat to drink; allow it to sip voluntarily.

Monitor vital signs. Check respiration rate, pulse (felt at the femoral artery), and behavior. Normal breathing is rapid but not labored; a weak pulse or unresponsiveness indicates severe distress.

Provide a safe, cool environment for recovery.

Place the rat in a cage with a temperature of 20‑22 °C (68‑72 °F).
Supply bedding that does not retain heat, such as paper strips.
Ensure adequate airflow without drafts.

Assess for signs of heatstroke. Look for:

Reddened or pale skin.
Disorientation, lethargy, or seizures.
Excessive drooling or panting.

If any of these symptoms are present, seek veterinary care promptly. Heatstroke can progress rapidly and may require injectable fluids or medications.

Prevent future incidents.

Keep cages or play areas out of direct sunlight.
Provide ample hiding spots and cool zones.
Limit outdoor exposure during peak heat hours (10 a.m. – 4 p.m.).
Ensure the animal has constant access to fresh water.

Prompt removal from heat, gentle cooling, and close observation are essential steps to rescue an overheated rat and reduce the risk of lasting damage. If uncertainty remains about the animal’s condition, professional veterinary assistance should be obtained without delay.
