What is a Fever in Pets and Why is it a Concern?
How to identify if your pet has a fever, and what does it mean?

Fever, in simple terms, is an elevation of body temperature above normal.
In humans and animals, it is a sign that the body is fighting something. It could be an infection, inflammation, or other health conditions.
It is crucial to understand that fever is not a disease in itself, but a symptom.
It indicates that your pet's immune system is actively working.
However, very high temperatures can be dangerous and require attention.
Normal body temperature varies between species.
For dogs, for example, the average is around 38.5°C to 39.5°C.
Cats generally stay between 38.0°C and 39.2°C. Small variations are expected.
More important than the exact number is observation. A fever can be an indication of something serious. Ignoring it can lead to complications or delay diagnosis.

Beyond the Thermometer: Behavioral Warning Signs
The good news is that our pets give us clues. They communicate through their behavior, even without speaking.
An attentive tutor can pick up on these subtle signs that something is not right.
When a fever sets in, the animal's body changes. These changes manifest themselves in a series of atypical behaviors.
The key is to get to know your pet on a day-to-day basis.
What is his routine? What are his normal habits? This knowledge base allows you to identify deviations.
Behavior is a powerful thermometer when interpreted well. See some signs below!
#Letargy and Decreased Activity when identifying whether the pet has a fever
One of the first and clearest signs is lethargy. Is your pet quieter than usual? Less likely to play or go for walks?
He can spend most of his time lying down.
Interest in activities that were once enjoyed decreases dramatically. This apathy is a strong indication of malaise.
A cat that normally runs around the house may end up huddled in a corner.
A playful dog may not want to fetch the ball. Watch his energy.
#Loss of Appetite and Excessive (or Absent) Thirst
Fever is often accompanied by loss of appetite.
Does your pet refuse to eat or eat much less than usual? This is a worrying sign.
Despite the fever, some animals may drink more water.
The body tries to cool itself and compensate for dehydration. Others, paradoxically, may refuse water.
Dry mouth and sticky gums are signs of dehydration.
Both scenarios – excessive thirst or absence – require attention.

#Changes in Sleep and Posture
When identifying whether your pet has a fever, observe their sleep pattern.
Your pet may sleep more than usual, but in a restless manner. Or, on the contrary, they may have difficulty resting.
Observe posture. An animal with a fever may curl up. It may adopt positions that indicate discomfort or pain.
The coat may appear more frizzy or dull. This is due to dehydration and general malaise.
#Tremors and Chills
Just like in humans, tremors are a common way to identify whether your pet has a fever.
The body tries to generate heat to combat whatever is causing the temperature to rise.
You may notice small muscle tremors.
In some cases, the animal may appear cold, even in a warm environment.
These chills are a physiological response of the body.
They are a clear sign that something is not right with the thermal regulation.
# Round Eyes, Dry and Hot Nose to identify if the pet has a fever
Your pet's eyes may appear more bloodshot.
They may be red or have a different shine. This is an inflammatory response.
The nose, which is usually moist and cold, can become dry and hot.
This is one of the most popular tips, but it should be used with caution. A dry nose does not always indicate a fever.
However, if combined with other signs, a warm, dry nose reinforces suspicion. Gently touch the nose to feel the temperature.
#Gengivas and Ears Warm
The gums and ears are areas where heat can be felt most easily.
Touch your pet's gums. They should be moist and pink.
If they feel warm to the touch, pale, or red, this could be a sign. The ears also tend to feel warmer.

Gently compare the temperature of your ears with other parts of your body.
A noticeable difference is an indication.
Real Cases: Observation in Action (How to Identify if Your Pet Has a Fever)
To illustrate the importance of observation, let's look at two practical examples of how identify if the pet has a fever just by behavior.
Example 1: Luna, a 5-year-old poodle, has always been extremely active.
He ran in the park, jumped and constantly asked for affection.
One day, her guardian noticed that Luna was lying in the corner of the room, something unusual. She refused her morning food, which was her favorite.
When he called her for a walk, Luna just raised her head and went back to lying down.
Her owner noticed that her ears were noticeably warmer and that she was shivering slightly.
These combined signs — lethargy, loss of appetite, hot ears and tremors — led the owner to seek a veterinarian immediately, confirming the fever.
Example 2: Tom, a 2-year-old Siamese cat, loves to climb and play with feathers.
Your routine includes several hours of naps and moments of pure energy.
One morning, his owner noticed that Tom hadn't climbed up onto his favorite scratching post. He was quiet, curled up under the bed, an unusual behavior.
When trying to interact, Tom reacted with disinterest.
His owner noticed that the tip of his nose was hot and dry, and his gums were a little paler.
A visit to the vet revealed that Tom had a high fever and needed treatment.
The Power of Tutor Intuition
An owner's intuition is a powerful tool; you can easily identify if your pet has a fever. You know your pet better than anyone else. Small changes in their daily behavior can be alarming.
Trust your instincts. If something feels “off,” it probably is. Don’t hesitate to seek professional guidance.
Veterinary medicine has advanced a lot. Today, we have more resources to ensure the health of animals. Information is your greatest ally.
When Observation Is Not Enough: Seeking Professional Help
Although observation is vital for identify if the pet has a fever, it never replaces veterinary diagnosis.
If you notice any of these signs, a professional should be consulted.
A veterinarian can perform accurate tests.
He will determine the cause of the fever and the appropriate treatment. Self-medication is extremely dangerous for pets.
Remember that some human medications are toxic to animals. Never risk your pet's health.
The Importance of Body Temperature in Different Species
Understanding temperature variations is essential. Let's look at a table with the average body temperature of some common pets:
| Animal | Normal (Average) Temperature |
| Dog | 38.5°C – 39.5°C |
| Cat | 38.0°C – 39.2°C |
| Rabbit | 38.5°C – 40.0°C |
| Ferret | 37.8°C – 40.0°C |
It is important to note that these are averages and there may be slight individual variations.

Sometimes the fever can be subtle.
Especially in older animals or those with chronic conditions. In these cases, observation must be even more acute.
An animal that already has a calmer routine may not show such obvious signs of lethargy.
Here, attention to detail makes all the difference.
Changes in appetite, hydration and social behavior may be the only clues.
Pay attention to any changes, no matter how small.
The Impact of Observation to Identify if Your Pet Has a Fever
A recent survey, published in 2024 by Journal of Small Animal Practice.
It revealed that 65% of the early diagnoses of febrile conditions in companion animals were driven by careful observation by owners, even before temperature measurement.
This highlights the importance of our role in the health of our pets.
It's like a car that starts making a strange noise.
You don’t have to be a mechanic to know something is wrong. Your instinct that “something doesn’t sound right” is the first and most important step.
Likewise, your pet is giving you “warning signals.” Are you paying attention?

Self-medication is dangerous and can worsen your pet's condition. Always consult a veterinarian.
3. How can I tell if my pet has a fever at home without a veterinary thermometer?

Only a veterinarian can diagnose the exact cause.
6. Why do some pets shiver when they have a fever?
To identify if your pet has a fever, observe the tremors, which are the body's natural response to generate heat.
