How to measure the cat's body temperature


Fever is usually a symptom associated with an infectious cause, whose main signal is the increase in body temperature.

Regardless of the cause that causes it, fever is always a sign that your cat is suffering from some kind of disease or health problem, so identifying it as soon as possible is essential to detect the focus and start the best treatment as soon as possible.


As with people, the most accurate way to know if your cat has a fever is to take the temperature. To do this you must introduce a thermometer into your rectum, or go to the veterinarian to be him who does it. If you have an adult cat, its usual temperature is 38º to 39º, and if it is a puppy of 39.5º. Be adult or puppy, if you exceed these parameters, you can confirm that you have a fever.

Other signs that can guide you to know that a cat has a fever are the following:

- Touch his nose. As with dogs, your pet's nose should always be wet. Cats with fever have it dry and hot.

- Observe their behavior, especially if they are restless or distressed for no apparent reason. And, also, if you notice it visibly affected or stay in bed for the most part, with heavy or irritated eyes.

- Look at his breathing and his heartbeat. Another indication that he is feverish is given by the fact that both aspects are more accelerated than normal.

- Stay alert regarding your personal hygiene. Cats are very clean. Neglecting their daily grooming is not their own, and is a clear indication that your cat is not in perfect condition.


If you detect any of these behaviors, proceed as follows:

- It is important that you keep it well hydrated. If your cat does not want to drink, you should provide him with the amount of liquid he needs with the help of a syringe. Insert it gently into your mouth, and empty the contents carefully. You can also give it an isotonic drink without gas.

- To avoid malnutrition, provide a food that meets your nutritional needs and, at the same time, is palatable. Make sure you don't have diarrhea, and opt for a wet diet. Once recovered you can combine it again with your usual dry diet.

- Place it in a quiet room, to be able to be with tiled floor, and slightly moisten the surface of your body. Help yourself with wet packs. Wet them slightly with cold water, place them on your forehead and let them act for a few minutes. Subsequently, remove them, and apply them on their legs and the abdomen area. Repeat the same process about twice a day. You can also place a fan near your cat to circulate the air, although you should never direct it directly towards it.


Keep in mind that the causes of your cat having a fever can range from mild issues to more serious illnesses that can even end your cat's life.

It is also true that not all pathologies manifest themselves through this symptom. The most common are:

- Presence of tumors that affect, above all, elderly cats.

- Viral or bacterial diseases, such as panleukopenia or leukemia.

- Viral, bacterial or fungal infections of a milder nature.

- Flu or common cold.

- Side effects due to the intake of any medication.

Of course, if your cat's temperature exceeds 41 ° C, you should go to the vet immediately to examine it, and determine the origin of the temperature rise. He, after doing the relevant exploration and determining the severity, will provide you with the appropriate treatment, and will tell you what you should do before this process.

How to measure the cat's body temperature

Armpit temperature

This method is less reliable to take the rectal or ear temperature. You must hold the cat with one hand and with the other place the thermometer under the armpit, preventing it from moving.

Temperature in ears

For restless cats, an ear thermometer may be a good option. To place it correctly inside the ear canal it is advisable to ask someone to help you hold the cat, add it by the back of the neck to immobilize the head, insert the thermometer into the ear in horizontal angle, wait for the thermometer alarm to sound that the reading is complete and remove it.

When the ideal temperature for a cat is taken in the ear is 38.55 degrees Celsius, although the normal variation is somewhat wider and can range from 37.77 to 39.44 degrees Celsius.

Straight temperature

Rectal thermometers give a temperature more precise, although your cat may like it less and if he is restless even less. Ask a person to help you hold the cat, you can help immobilize it by wrapping it in a small towel, and hold the cat in the arms leaving the rear out. Lubricate the thermometer with petroleum jelly or a lubricant, lift the tail and gently insert it into the rectum about 2 cm without forcing. If it is a digital thermometer, wait for the signal and if it is mercury, leave it within 2-3 minutes. Check the temperature. For hygiene do not forget to wash the thermometer well with water and soap or alcohol.

The normal rectal temperature of the cat is between 37.8-39.2 degrees Celsius.

Before a variation of normal body temperature do not hesitate to go to the veterinarian.
