Heat Stroke in Cats: Symptoms, Risk Factors, Prevention and Care

It is extremely important to keep a close eye on your pet’s health. Your beloved pet may not be able to complain but it can go through certain health problems that you should be aware of. Heat stroke is one such problem and it is more common in cats than you may want to believe. This condition is also known by many other names such as hyperthermia, heat stress and heat exhaustion.

Your furry friend is at risk of this malign when the surrounding or outside temperature reaches too high and as a result, the poor animal’s bodily functions are not able to regulate it. Generally, a temperature above 104 degrees Fahrenheit or an equivalent of 40 degrees Celsius is assumed to be the limit a cat can endure. If this is surpassed then it will lead to overheating or a heat stroke. But worry not! Because this article will walk you through all you need to know about heat strokes in cats including symptoms, risk factors, reasons, precaution, prevention, and all other essential information.

Why Is It Important?

Heat stroke or hyperthermia in cats can have fatal consequences. Although contrary to the popular belief that cats are a desert animal, they have weak heat-regulating mechanisms, due to which it is not abnormal for them to get a heat stroke. In extreme cases, this can lead to life-threatening consequences. There have been reported cases of heat strokes in cats which lead to malfunction of organs, multiple organ failure, intestinal bleeding, and other perilous health conditions. In severe cases, it has also been a cause of death. Thus it is extremely crucial that you are aware of the symptoms and risk factors so that you can take action as promptly as possible and save yourself and your cat from a life-altering experience. Taking good care of your pet’s health is an essential part of nurturing and loving it; more so when it is completely dependent on you for its food, shelter, and survival.

What Is the Primary Reason for Heat Stroke in Cats?

A heat stroke or heat stress typically occurs in cats when the cat’s elevated core body temperature rises above the normal range. A cat’s normal body temperature is between 100 to 103 degrees Fahrenheit (or 38 and 39 degrees Celsius). If the core body temperature reaches beyond this, it is harmful because your cat will not be able to get rid of the excess heat as fast as it is required at that situation. Cats do not have many sweat glands to get rid of the excess heat; only a few in their paws and around their nose. Furthermore, they have a much thicker coat of fur that lines their entire body. These features elevate the risk of heat stroke in cats, which is why they are more susceptible to damage and are poorer temperature regulators.

What Are the Risk Factors of a Heat Stroke in Cats?

Like all other things, there are certain factors that make cats more susceptible to a heat stress. Some of these can be avoided and some cannot. These risk factors are:

  • Adults of greater age: Elderly cats are at higher risk of getting a heat stroke as age makes it tough for them to regulate their body temperature.
  • Overweight and obesity: Overweight cats are more open to getting a heat stroke than average ones. Due to their large mass, it takes less effort for the heat to get them.
  • Breed of a cat: Certain cat breeds are proven to be more at risk of getting a heat stroke than others. Especially the ones with features such as flat faced and stubby nose, who are also known as “brachycephalic” cats. These cats include the species: Persian, Himalayan, British Shorthair, and Scottish Fold.
  • Chronic and acute illnesses: Existing illnesses is also a predisposing factor putting your cat at a higher risk of attaining heat stroke. Health conditions such as respiratory, cardiovascular, neurological or kidney disease pose a higher risk of heat stress.
  • Excessive exercise: Despite exercise being good for your cat’s overall health, excessive exercise is not a good idea during hot and humid days. This will make your cat go warm very fast.
  • Environmental factors: Some environmental factors such as high temperatures and excess sunlight are also risk factors of attaining heat stress.
  • Surrounding conditions: The surrounding factors such as a poorly ventilated place, dry and confined space or an area with a lack of water also pose an increased risk.
  • Coat of fur: A coat of fur all over the animal’s body naturally makes its temperature high. Cats with dark colored, long and thick fur are easy targets because of their better-insulated bodies and better heat absorption capabilities.

  • Sweating from the feet: Cats do not have many sweat glands to dissipate its body heat; paws are one of the very few places which allow it to do so. Thus if your cat is sweating from the paws it is a signal that the cat is getting rid of excess heat from its body.
  • Drooling and salivation: Your pet cat will exhibit some abnormal behavior one of which is excessive drooling and salivation; this is a sign of heat stress. You can also check if the saliva is sticky to be sure.
  • Bright red tongue: If you see that the color of your cat’s tongue has changed from pink to a bright red, it is a matter of concern because heat stress sometimes leads to that.
  • Pale or dark red gums: Another oral symptom of heat stroke is pale or dark red gums. Although sometimes it may indicate other things, this is often a sign of heat stress.
  • Weakness and fatigue: Most cats are lethargic by nature and like to lie around royally in their kingdom, but if you notice your cat is awake but not alert or moving, it can be due to heat stroke.

  • Little to no urine production: Heat stress causes some bodily changes one of which is a change in the production of urine. This is also a sign of fatigue and dehydration.
  • Glazing and red eyes: Just like we humans tend to have glazing red eyes when we feel extremely hot, so do cats. Only they cannot communicate with us! So look out for this sign of a heat stress.
  • Unnecessary grooming: Often cats start to groom themselves unnecessarily while experiencing a heat stroke. They do this thinking that it will bring down the temperature.

Heat Stroke Prevention for Cats

Despite the fact that there are so many conditions and predisposing factors which pose a greater risk of your cat getting a heat stroke, there is an equal number of prevention factors as well, maybe more! There are many things which you can do to prevent and save your cat from getting a heat stroke, some of which are:

  • Keep your cat around or near you at all times, especially during hot days. By monitoring the cat well you can know in what condition your cat is and what it is up to.
  • Set a proper living space for your cat. Your cat must have easy access to shade and water. You must ensure proper ventilation at the spot and see that direct sunlight does not fall upon it.
  • Introduce some changes to your pet’s eating habits. It is advised to feed your cat canned food if you already do not do so. Adding water or tuna water to regular cat food is also encouraged to increase its fluid intake.
  • Keep your cat hydrated at all times, both internally and externally. Your cat should have a bowl of water or a cat water fountain within its vicinity all the time so it can drink from it and also wash when needed.
  • Do not leave your cat alone in the laundry room or vehicle alone. Often, cats somehow end up in the drier and this results in fatal consequences. The temperature in a closed car can rise rapidly and if your cat is stuck in there, it will definitely face a heat stroke. An easy solution is to turn the air conditioner on or to keep the windows slightly ajar for air to pass.
  • Choose the environment that best suits the need of your cat. If your apartment does not have air conditioning and proper ventilation, then let it get some fresh air from outside. However, if it is a very hot and humid day, keep it hydrated and cool indoors.
  • Avoid hot and flat surfaces for play areas. Do not leave your cat unattended or let it play on hot sand or a sandbox on warm summer days. Temperatures in there soar up pretty fast. Also, avoid concrete or asphalt areas where there is no room for heat to escape and rather it is absorbed.
  • Do not let your cat do excessive exercise on hot and humid days. Exercising makes the body temperature go up and releases a lot of sweat. This can make your cat more prone towards attaining a heat stress.
  • Act sensibly. Know and understand the symptoms of heat stroke and act accordingly. If you detect our cat got a heat stroke, after all, play smart and act quickly. Take the best decision that suits the condition of your pet cat.
  • Get a regular checkup and consultation from your veterinarian. Whether or not your cat is suffering from health conditions, it is always a good idea to keep a close eye on its health. This way you can also find out which diet suits your pet best and whether it is overweight or not.

Treatment for Heat Stroke in Cats

What if somehow you end up in the unwanted situation of your cat getting a heat stroke? Fortunately, there are many treatment options for a heat stress. Knowing them will help you during times of hopelessness and distress; you will know what to do then. In mild heat stress conditions, there are many things that can be done at home to treat heat stroke, which are:

  • Immediately remove your cat from the hot place and put it in a cooler zone. If an air-conditioned room is available, then that is the best possible choice. This will start to stabilize body temperature.
  • Apply water on the cat’s fur and skin. This can be done by spraying water or by rubbing a wet cloth over the pet’s skin. Either way, the core temperature will start to come down.
  • Be careful not to use ice cold water as it will make the problem worse; tepid water is optimal. A sudden drop in temperature will lead to hypothermia which is why a gradual decrease is a preferable alternative.
  • Fan your cat. This way air will reach in between the furs and maximize heat loss. This will show the best results if it is paired with spraying water on your cat.
  • Keep an eye on the temperature. Measure the cat’s temperature after five-minute intervals to keep a check and continue cooling if needed. When the temperature reaches 103 degrees Fahrenheit (or 39 degree Celsius), it is back to normal.

However, despite taking these measures, a veterinarian check up is always absolutely mandatory. Starting the treatment earlier at your home substantially reduces risks but your vet is a professional and will definitely know better how to treat your cat. This is also advisable to avoid further complications and be safe. What your vet might do is:

  • Run blood tests and urine analysis to ensure it is a heat stroke and not an infection.
  • Provide ice packs and closely monitor temperature. This remedy can also be started at home.
  • Inject an intravenous (IV) fluid line to your cat’s body so that cool and hydrating fluids run directly into its body. This will also stabilize it and reduce risks of organ damage.
  • In more extreme cases, oxygen therapy and admission to the hospital may be required.

This was your complete guide to the know-how of recognizing and properly treating a heat stroke in your cat. Despite proper prevention, if a heat stroke still occurs, there is a chance of recurrence thus keep your vet close by! Good luck to you and your cat/cats and happy petting!
