What is the normal body temperature for cats and dogs?

Normal body temperature: Cats: 38.0°C – 39.2°C. Dogs: 37.5°C – 39.0°C. Above the upper limit = fever (hyperthermia). Below the lower limit = hypothermia, also dangerous. For context: normal human temperature is 36.1–37.2°C, so pets naturally run warmer than we do.

Does a dry or warm nose mean a cat has a fever?

No — this is a very common myth. A cat's or dog's nose can be dry and warm just after waking up, after sunbathing, or in hot weather — with no fever at all. The only accurate way to know your pet's temperature is with a thermometer.

What thermometer is best for cats and dogs?

Best for accuracy: a digital rectal thermometer. More comfortable but slightly less accurate: infrared ear thermometer (make sure it's designed for animals). Not recommended: oral human thermometers (not accurate under the armpit/axilla), forehead infrared thermometers (designed for humans, not accurate for pets). An inexpensive digital rectal thermometer (IDR 50–150k) is the best choice for home use.

My cat has a temperature of 39.5°C — does it need a vet?

It depends on the overall condition. 39.5°C is slightly above normal (upper limit 39.2°C). If the cat is still eating, drinking, and active — monitor for 12–24 hours. If temperature ≥40°C, or 39.5°C with other symptoms, consult a vet. Fever ≥41°C is a medical emergency.

What can be done to reduce a cat's/dog's fever at home?

For mild fever: ensure the animal is hydrated (encourage drinking), place in a cool and well-ventilated room. NEVER give paracetamol, ibuprofen, or aspirin — these are all toxic to cats and dangerous to dogs. Fever ≥40°C or not improving within 12 hours = contact a vet.

How to Measure Temperature: Rectal Method (Most Accurate)

The rectal method is the gold standard for measuring a pet's temperature — it gives the most accurate result.

1

Prepare the digital thermometer and lubricant

Lubricate the tip with petroleum jelly (Vaseline) or KY gel. Turn on the thermometer and wait for the ready signal.
2

Position the animal

Cats: gently hold on a table in a standing position or lying on its side. One person holds the body and head, the other takes the measurement.
3

Insert the thermometer

Lift the tail gently, insert the tip of the thermometer about 2–3 cm (1–1.5 inches) into the rectum. Don't force it if there is resistance.
4

Wait for the beep, then read the result

Clean with alcohol after use.

Interpreting the Result

Below 37.5°C

Hypothermia

Temperature too low. Could indicate shock, poisoning, or a critical condition. Warm the animal slowly and contact a vet immediately.

38.0–39.2°C

Normal

Temperature within normal range.

39.3–40°C

Mild Fever

Monitor closely. If still active and willing to eat, observe for 12–24 hours. If not improving or other symptoms appear, contact a vet.

Above 40°C

Serious Fever — Contact a Vet

Above 41°C is a medical emergency — can cause permanent organ damage.

What NOT to give a pet with a fever:

Paracetamol (acetaminophen) — HIGHLY TOXIC to cats, dangerous to dogs
Ibuprofen — toxic to cats and dogs, causes kidney failure
Aspirin — toxic to cats
