Taking your cat’s temperature under the armpit is a gentle way to check your pet’s health when you want to avoid stress.
Though not as precise as rectal readings, it can still give you a quick idea of your cat’s body temperature when done carefully. This article explains how to perform this method safely, what accuracy to expect, and when to see a veterinarian.
Why and When to Take a Temperature
Monitoring temperature helps detect fever, infection, or low body temperature. According to the American Veterinary Medical Association, a normal cat’s temperature ranges between 100.5°F and 102.5°F.
Taking your cat’s temperature under the armpit can help when your pet feels unwell and you need a fast reading without causing discomfort. It’s especially useful for anxious or older cats that dislike being handled too much.

How to Take Your Cat’s Temperature Under the Armpit
- Choose a calm moment when your cat is relaxed.
- Use a digital thermometer specifically designed for pets (or one dedicated solely to your cat).
- Gently place the thermometer tip in the inner armpit (axilla) and hold it there for a few seconds until you get a stable reading.
- Record the temperature, compare it with normal ranges, and clean the thermometer after use.
When taking your cat’s temperature under the armpit, make sure to interpret results carefully. The reading can be slightly lower than the true body temperature since the armpit does not always reflect internal temperature accurately.

Accuracy and Research Insight
Research shows that readings taken from the armpit (axillary region) can vary compared to rectal measurements.
A study in the Journal of Feline Medicine and Surgery found that axillary temperatures differed by up to 1.4°C from rectal ones. Another report by the University of Liège noted that only about 78% of armpit readings were within 0.5°C of rectal results.
This means taking your cat’s temperature under the armpit should be viewed as a screening method rather than a diagnostic one.
Still, it is a good first step at home. If the reading appears abnormal or your cat shows signs of illness, such as shaking, hiding, or refusing food, seek professional help.

When to See a Veterinarian
If your cat’s temperature seems higher or lower than normal and your pet appears weak, panting, or refusing to eat, it’s time to call your veterinarian.
Cats can mask illness, so even mild symptoms should be checked. Your vet may confirm the reading using a rectal thermometer for accuracy and evaluate for infections or other conditions.
Veterinarians rely on multiple signs, not just temperature. They may also check hydration, heart rate, and gums. A study in The Veterinary Journal confirmed that combining physical exams with rectal temperature readings offers the most reliable health assessment.

What to Expect During Your Visit
During your visit, your veterinarian will:
- Take your cat’s rectal temperature using a pet thermometer.
- Examine the ears, eyes, mouth, and overall body condition.
- Ask questions about symptoms, appetite, and recent changes in activity or mood.
- Possibly perform tests like blood work or urinalysis if infection is suspected.
- Recommend treatment or home monitoring depending on the cause.
The appointment helps you get a clear diagnosis and ensures your cat gets the care it needs quickly.
