What is it?
Heatstroke is a life-threatening emergency. It occurs when the wallaby's body temperature exceeds what its body can regulate.\n\nThis animal, native to Australia, does not tolerate high heat and especially high humidity combined with a lack of shade or water. In Tunisia, hot and dry summers can expose wallabies held in parks or in private captivity to this risk, particularly during peak heatwaves. Without rapid intervention, heat stroke can lead to death within a few hours.
Key point
Heatstroke is an absolute life-threatening emergency for wallabies: without rapid intervention, it can lead to death within a few hours.
Commonly observed signs
These signs are neither exhaustive nor specific. Only a veterinarian can establish a diagnosis.
Related signs — each one links to its page:
The wallaby suffering from heat stroke breathes quickly, sometimes with its mouth open, and drools excessively.\n\nIt becomes abnormally calm or on the contrary agitated, seeks shade without succeeding in cooling itself, and can stagger as if it were losing its balance.\n\nIn severe forms, the animal remains lying down, no longer gets up, presents tremors or convulsions. The gums and the inside of the lips may appear pale or, on the contrary, very red.\n\nThese are signs of absolute emergency.
When to consult without delay
This list does not replace veterinary advice. It gathers situations that justify a prompt consultation.
Causes and risk factors
The direct cause is an excessive and prolonged rise in body temperature. It occurs when ambient heat exceeds the wallaby's ability to dissipate its own heat, in particular by licking its forearms which is its main means of natural cooling.\n\nHigh humidity aggravates the phenomenon because it prevents the effective evaporation of saliva and sweat.
Lack of shade or shelter in the enclosure.\n\nLack of a permanently accessible fresh water source.\n\nExercise or transport during the hottest hours of the day.\n\nOvercrowded or poorly ventilated enclosure.\n\nYoung, old, sick or overweight animal, more vulnerable to heat.\n\nThick coat or lack of gradual acclimatization to high heat.
Diagnosis and care
Diagnosis is the veterinarian's responsibility, based on clinical examination and laboratory tests. Care is decided case by case.
The veterinarian urgently assesses the body temperature and the general condition of the animal.\n\nHe looks for signs of shock, dehydration and suffering of the internal organs, sometimes through additional blood tests.\n\nThe diagnosis is mainly based on the context, the recent ambient heat, and the symptoms observed.
Treatment
Treatment is an emergency and aims for a gradual and controlled cooling of the animal, never sudden.\n\nIt may include fluid therapy to correct dehydration and support circulation, as well as supportive care depending on the state of the affected organs.\n\nNo home treatment should replace immediate veterinary consultation.
Treatment depends on the cause and the animal's condition: it must be determined by a veterinarian. No self-medication.
Prevention
Provide permanent natural or artificial shade in the enclosure, as well as free access to fresh water.\n\nInstall shallow basins or humidified areas allowing the animal to cool itself.\n\nAvoid any transport, handling or physical exertion during the hot hours of the day, especially in summer.\n\nMonitor the animals closely during peak heatwaves and adapt the enclosure if necessary, by example with a mister or a fan.\n\nGradually acclimate a newly arrived animal to a warmer climate.
Possible complications
Heatstroke can seriously damage the kidneys, liver and nervous system.\n\nBlood coagulation disorders and generalized shock may appear in severe forms.\n\nEven after apparent recovery, internal after-effects are possible and require veterinary supervision.
When to see a veterinarian
The wallaby breathes unusually quickly or panting.\nIt drools excessively or seems unable to cool itself despite the shade.\nIt staggers, seems disoriented or suddenly changes behavior.\nIt remains lying down and does not get up.\nIt exhibits tremors or convulsions.\nAny suspicion of heat stroke after prolonged exposure to high heat.
Prognosis
The prognosis depends on the speed of treatment. Heat stroke recognized and treated early has a better chance of recovery without after-effects.\n\nIn case of delay in treatment or severe form, the prognosis becomes guarded, with a risk of lasting internal complications or death.
Frequently asked questions
How do I know if my wallaby has heat stroke?
The main signs are rapid or heavy breathing, excessive salivation, a staggering gait or an animal that remains lying down without getting up. Any exposure to high heat associated with these signs should alert you immediately.
What to do while waiting for the vet?
Move the animal to the shade in a cool, quiet place, without handling it roughly. Never immerse the animal in ice water, too sudden cooling can worsen its condition. Contact a veterinarian urgently.
Do wallabies tolerate the Tunisian climate?
Wallabies are native to temperate to cool regions of Australia and do not tolerate high summer heat well. In detention in Tunisia, they absolutely require shade, fresh water and increased supervision in summer.
Can a wallaby relapse after a first heatstroke?
Yes, an animal that has already suffered from heatstroke may retain increased sensitivity to heat. Reinforced prevention is recommended for the following summers.
