How Do You Take a Hamster's Temperature?

Taking your hamster’s temperature is an important part of monitoring their health and wellbeing. As prey animals, hamsters are excellent at hiding illness,

so noting any changes in your hamster’s normal temperature can help alert you early on to potential health problems. With some preparation and care, taking your hamster’s temperature at home can be quick and stress-free.

Why Take Your Hamster’s Temperature?

A normal hamster’s body temperature ranges from 99°F to 104°F (37°C to 40°C). Taking your hamster’s temperature allows you to:

Monitor any changes in their normal temperature over time. Fluctuations can indicate illness or stress.
Get an early diagnosis. Changes in temperature often occur before other obvious symptoms of illness.
Track their recovery. You can see if their temperature is returning to normal with treatment.
Avoid extremes. Temperatures over 105°F or under 97°F require emergency veterinary care.

Regular temperature checks along with weighing your hamster weekly provide key information on their health and well-being between vet visits. For a new hamster, take their temperature 2-3 times when they are settled to establish their normal range.

Choosing a Thermometer

To take your hamster’s temperature, you need a suitable thermometer. The options are:

Digital thermometer – Easy-to-read LCD display. Fast and accurate. Can be used for rectal, oral, or axillary temperature.
Infrared thermometer – Used to take a surface temperature reading. Less invasive than other methods.
Traditional glass thermometers are cheap but run the risk of breaking and containing mercury. Harder to read and clean properly.

Veterinarians recommend using a digital thermometer for taking small pet temperatures. They provide the most accurate readings while being safe and easy to use.

Look for one with a narrow, flexible probe and a 1-2 second response time. Choose between a rectal or general-purpose thermometer depending on how you plan to take your hamster’s temperature.

Preparing For a Temperature Reading

Taking your hamster’s temperature will be quicker and less stressful when you’re prepared. Here are some tips:

Set up in a quiet room away from other pets or household noise and chaos. Have everything close at hand.
Allow time for a careful approach. Don’t rush handling your hamster. Let them sniff and explore first.
Have a helper. They can assist in positioning your hamster while you focus on taking the temperature.
Offer a treat after to help make it a positive experience and reassure your hamster.
Take their temperature when they are awake and active. Don’t disturb their sleep.
Handle them securely but gently. Keep them warm and constrain them minimally.

With care and patience, regular temperature checks can become routine. However, if your hamster shows signs of distress, stop and try again later. Seek advice from your vet if you are unable to take their temperature after multiple attempts.

How To Take a Hamster’s Temperature

There are three main options for taking your hamster’s temperature:

1. Rectal Temperature

Taking a rectal temperature gives the most accurate reading but requires care and patience:

Hold the hamster securely on its back or side, gently grasping the scruff.
Apply a small amount of petroleum jelly to the end of the thermometer for lubrication.
Gently insert the thermometer 1⁄2 to 1 inch into the rectum angled slightly toward the tail.
Hold in place while awaiting the digital readout (usually under 10 seconds).
Sanitize the thermometer thoroughly afterward with soap and water.

Rectal readings provide the true core temperature but the process can be stressful for a hamster. Go slowly and offer reassurance.

2. Oral Temperature

An oral temperature reading is less invasive while still accurate when done carefully:

Position the hamster with the head gently restrained.
Place the thermometer tip under the tongue near the rear molars.
Hold gently until the thermometer signals are done.
Remove carefully and sanitize the thermometer.
Ensure no damage was done to teeth or gums.

To get an accurate oral reading the hamster must sit still with mouth open. This takes more time and patience but avoids rectal insertion.

3. Axillary Temperature

Taking an axillary or underarm temperature is the least invasive option:

Hold the hamster on its back and gently stretch a front limb sideways to expose the armpit.
Place the thermometer tip vertically into the hairless area. The tip should have skin contact.
Hold gently in place until thermometer signals are complete.
Slowly remove and sanitize the thermometer.

The fur in the armpit traps body heat to allow an accurate reading. However, axillary temperatures run 1-2 degrees lower than core temperature normally.

Interpreting the Temperature Reading

Once you have a temperature reading, you can compare it to the normal range. Here are some guidelines:

100-103°F (37.7-39.4°C) – Within normal range. No concern.
Under 99°F (37.2°C) – May indicate illness or hypothermia. Call your vet.
Over 104°F (40°C) – Risk for hyperthermia or fever. Have vet assess urgently.
Over 105°F (40.5°C) – Emergency hyperthermia. Seek immediate treatment.

Remember that each hamster has a normal range that may differ slightly. Look for any upward or downward changes in their regular temperature as the most meaningful indicator of concerns.

Tips for Less Stress During Temperature Taking

While taking your hamster’s temperature is quick, it can still be stressful. Here are some tips to make it easier for both of you:

Go slowly with plenty of sniffing time before restraint.
Offer small treats after as positive reinforcement.
Keep handling gentle but secure to avoid escape attempts.
Make it a two-person job with one restraining and one taking temperature.
Start young to get them used to the routine early on.
Try different thermometer positions to see which they prefer.
Avoid temperature taking when they are sleeping or seem distressed.
Keep patient and calm throughout the process. Your hamster will pick up any anxiety.

With time and consistency, regular temperature checks will become a regular part of your hamster’s healthcare routine.

Signs of Health Concerns Requiring Veterinary Assessment

While most temperature fluctuations in hamsters are minor, some changes can signal health problems requiring prompt veterinary assessment:

Temperature over 105°F (40.5°C) – Emergency hyperthermia risk requiring cooling and fluids.
Temperature under 97°F (36°C) – Hypothermia requiring gentle warming and stabilization.
Temperature over 104°F (40°C) – Fever indicating infection or illness needing diagnostics and treatment.
Temperature spikes up and down – Significant unstable fluctuations between high and low.
New extremes – Well outside their normal range despite environmental control.
Prolonged change – Temperature stays significantly higher or lower for more than 48 hours.
Unexplained change – Shift up or down without reason like environmental temperature change.

Contact your exotic veterinarian for an urgent consult if your hamster exhibits any of these temperature changes along with lethargy, appetite changes, or other concerning symptoms. Rapid treatment greatly improves the prognosis in unwell hamsters.

When to Take Your Hamster’s Temperature

While having one baseline temperature reading is useful, the real value comes from monitoring for any changes over time. Here are some key situations and times to take their temperature:

When you first get your hamster – Establish their healthy normal range.
If appetite decreases or seems unwell – An early sign to check for fever.
On return from boarding – Check for stability after time away.
During environmental temperature swings – Ensure housing temperatures are comfortable.
Baseline deworming or vet check – Compare before and after intervention.
Introduction to new hamster – Check for changes during quarantine.
After travel – Confirm no temperature impacts.
Biweekly or monthly – General monitoring for subtle shifts.

Listen to your gut. If your hamster seems even slightly “off”, take their temperature to get an objective reading on their wellness. Act promptly if the temperature indicates fever or hypothermia.
