What is the normal body temperature for a cat?
You're cuddling your feline companion and it feels warmer than usual, making you wonder what a normal body temperature for a cat actually is. A healthy cat's body temperature typically ranges between 38.0°C and 39.2°C (100.4°F–102.6°F). This is naturally higher than a human's body temperature due to, among other factors, a faster metabolism. If a cat's temperature drops below 38.0°C (100.4°F), it may indicate hypothermia. If it rises above 39.2°C (102.6°F), it may signal a fever, most commonly associated with infection, inflammation, or severe stress. To accurately determine whether your cat's body temperature is within the normal range, use a rectal thermometer, as it provides the most reliable measurement.

What Is a Normal Body Temperature for a Cat?
A healthy cat's body temperature typically ranges from 38.0°C to 39.2°C (100.4°F–102.6°F), which is higher than the average human body temperature of 36.6°C (97.9°F). However, a cat's temperature is not constant throughout the day and may vary depending on several factors, including:
Age – Newborn kittens have a lower body temperature than adult cats, typically between
35°C and 36°C (95°F–96.8°F). Their temperature gradually increases and usually stabilizes by around
four weeks of age.
Time of day – Body temperature may be slightly lower in the morning and higher in the evening.
Physical activity – Exercise and play increase metabolism and heat production in the muscles.
Stress – A cat's body temperature may temporarily rise during stressful situations, such as a visit to the veterinarian.
If your cat's temperature falls within the normal range and your pet is behaving as usual, there is generally no cause for concern. Persistent deviations from the normal range, especially when accompanied by additional symptoms, may indicate an underlying health problem.
Why Is a Cat's Body Temperature Higher Than a Human's?
A cat's higher body temperature is primarily the result of its faster metabolism. Cats have a higher metabolic rate than humans, meaning that the cellular processes occurring in their bodies generate more heat.In addition, because cats have a relatively small body mass compared to their body surface area, they lose heat more quickly than larger animals. To compensate for this, their bodies produce heat more efficiently, helping them maintain a naturally higher core temperature.
Hypothermia in Cats – When Is the Temperature Too Low?
Hypothermia occurs when a cat's body temperature falls below 38.0°C (100.4°F). This drop in temperature may result from prolonged exposure to cold weather, a wet coat, shock, or anesthesia. Low body temperature can also accompany certain metabolic disorders. Kittens, senior cats, and underweight cats are particularly susceptible to hypothermia.
The most common signs of hypothermia in cats include:
Severe muscle tremors or shivering
Marked lethargy, sluggishness, and apathy
Cold ears, paws, and tail
Slow breathing and heart rate
Difficulty maintaining balance
If you suspect your cat is suffering from hypothermia, move it to a warm environment as quickly as possible, wrap it in a blanket, and contact your veterinarian immediately.
Fever in Cats – When Is the Temperature Too High?
A cat is considered to have a fever when its body temperature exceeds 39.2–39.5°C (102.6–103.1°F). Fever is most commonly associated with infections, inflammation, and hormonal disorders. It may also occur as a response to stress or overheating, for example after spending a prolonged period in a hot, poorly ventilated room.
Common signs of fever include:
Lethargy
Excessive sleepiness
Reduced activity
Decreased appetite or complete loss of appetite
Rapid breathing
Ears and paws that feel warmer than usual
Hiding and avoiding human interaction
If you suspect your cat has a fever, consult your veterinarian as soon as possible. They will determine the underlying cause of the elevated temperature and recommend appropriate treatment.
Never give your cat human fever-reducing or pain-relieving medications, such as paracetamol (acetaminophen), ibuprofen, or aspirin. Cats cannot metabolize these drugs properly, and even small amounts can be highly toxic.
How to Measure a Cat's Body Temperature
The most accurate way to measure your cat's body temperature is with a rectal thermometer. Follow these steps to obtain an accurate reading:
Apply a small amount of petroleum jelly, baby oil, or a water-based lubricant to the tip of the thermometer.
Ask another person to gently restrain your cat. Wrapping the cat in a towel using the so-called
"cat burrito" technique while leaving the hindquarters exposed can help keep your pet calm and secure.
Carefully insert the thermometer approximately
1–1.5 cm (0.4–0.6 in) into the rectum.
Wait until the thermometer signals that the measurement is complete.
Remove the thermometer, disinfect it thoroughly, and wash your hands.
If your cat becomes extremely stressed during rectal temperature measurements, you may use a non-contact infrared thermometer, which can measure temperature around the ear area. This method is much less invasive, but it is not as accurate as using a rectal thermometer.
Never attempt to measure your cat's temperature orally. Your cat may bite the thermometer, potentially causing injury or damaging the device.
Normal Body Temperature in Cats – Summary
Regularly checking your cat's body temperature is one of the simplest ways to monitor its overall health. Keep the following key points in mind:
A cat's normal body temperature is naturally higher than a human's, ranging from
38.0°C to 39.2°C (100.4°F–102.6°F).
The most accurate way to measure your cat's temperature is with a rectal thermometer.
If your cat becomes highly stressed during the procedure, you may use a non-contact infrared thermometer, but remember that its readings are generally less accurate.
Hypothermia occurs when a cat's body temperature falls below 38.0°C (100.4°F) and is accompanied by symptoms such as shivering, lethargy, and cold ears, paws, or tail.
A fever is generally defined as a body temperature above 39.2–39.5°C (102.6–103.1°F), often accompanied by lethargy, drowsiness, loss of appetite, and unusually warm ears and paws.
Never give your cat human fever-reducing or pain-relieving medications. Always consult your veterinarian, especially if your cat's body temperature is significantly above or below the normal range.
