What is it?
Heatstroke is a life-threatening emergency. It occurs when the body temperature of the saïmiri (small squirrel monkey) rises too high and its body is no longer able to cool down. The saimiri is a small primate native to the tropical forests of South America, but it does not tolerate excessive heat combined with a lack of shade, water or ventilation. Without prompt intervention, vital organs can be damaged within minutes to hours.
The saïmiri with heat stroke breathes quickly and loudly, sometimes with its mouth open. He becomes despondent, limp, seeks to isolate himself or, on the contrary, becomes agitated without being able to calm down. His saliva flows excessively. The gums may turn pale or grayish instead of pink. In severe forms, the animal staggers, trembles, may convulse, then lie down without being able to get up. This is a sign of extreme emergency.
The direct cause is exposure to excessive heat: cage or terrarium in direct sunlight, poorly ventilated room, transport in a hot vehicle, summer heat wave, or overheated premises without air conditioning. The saïmiri regulates its temperature poorly when it does not have access to shade, fresh water or moving air.

When to consult without delay
This list does not replace veterinary advice. It gathers situations that justify a prompt consultation.
Causes and risk factors
Young people, elderly animals, weakened or sick individuals are more vulnerable. An enclosure without a shaded area, high humidity associated with high heat, the absence of a water point, prolonged transport without ventilation, or insufficient acclimatization during a recent change of environment also increase the risk.
Diagnosis and care
Diagnosis is the veterinarian's responsibility, based on clinical examination and laboratory tests. Care is decided case by case.
The veterinarian assesses body temperature, state of consciousness, color of mucous membranes and signs of shock. He can perform blood tests to check the condition of the organs (kidneys, liver) and look for clotting disorders, common in cases of severe heatstroke.
Treatment
Management aims to gradually lower body temperature through controlled cooling methods, stabilize circulation with intravenous fluids, and monitor vital functions. Supportive treatments for affected organs may be necessary depending on the severity.
Treatment depends on the cause and the animal's condition: it must be determined by a veterinarian. No self-medication.
Prevention
Always keep a shaded area and access to fresh water available. Avoid direct exposure to the sun, especially during the hottest hours. Ensure good ventilation or air conditioning in accommodation premises during hot periods. Never leave a saimiri in a closed vehicle, even for a few minutes. Monitor the animal carefully during heat peaks, particularly in Tunisia during the summer.
Possible complications
Severe heatstroke can lead to kidney and liver damage, blood clotting disorders, brain edema, or even death if treatment is not immediate.
When to see a veterinarian
Very fast or difficult breathing after exposure to heat
Sudden depression or refusal to move
Unusual excessive salivation
Tremors, convulsions or staggering gait
Pale or grayish mucous membranes
Lying animal that does not get up
Prognosis
The prognosis depends on the speed of treatment. Treated early, before serious complications develop, the squirrel can recover completely. After a certain period of time, the risk of after-effects or death increases sharply.
Frequently asked questions
Can a saimiri get heatstroke even in the shade?
Yes, if the ambient air is very hot and humid and ventilation is insufficient, shade alone is not always enough to prevent overheating.
What to do while waiting for the vet?
Immediately move the animal to a cool, ventilated place, never using ice water which can aggravate the shock, then contact a veterinarian urgently.
Can heatstroke recur?
Yes, an animal that has already suffered from heatstroke often becomes more sensitive to heat afterwards and requires increased monitoring.
