Ever wondered if your hamster sweats like you? Well, you’ll be surprised.

Do Hamsters Sweat?

Hamsters do sweat, but not quite like us humans or other animals.

The sweat glands in hamsters are primarily located on their feet, and they’re minuscule. Imagine a sweat gland the size of a pinhead!

Sure, it’s not a sight you’d want to see under a microscope, but it’s an interesting fact for sure. So, if you see your hamster’s tiny feet a bit damp, don’t worry – it’s just a little hamster perspiration at work.

But why don’t hamsters look sweaty?

The answer is pretty simple – their dense fur. It’s like a mini sweat-absorbing sponge.

Plus, they produce such a low amount of sweat that you’d need a magnifying glass to spot the difference.

Should I Worry If I Found My Hamster Wet?

It’s crucial to distinguish between a wet hamster and a hamster afflicted with wet tail disease.

If your hamster appears wet, several factors could be at play.

Maybe their water bottle is leaking, or they’ve had an encounter with damp bedding.

Remember, hamsters have scent glands on either side of their bodies, and they might be marking their territory, particularly if they’re adjusting to a new environment.

However, things take a severe turn if you observe a dirty, wet rear end accompanied by loose or bloody stools. This could signal wet tail disease, a condition that can prove fatal if left untreated.

So, yes, a wet hamster doesn’t necessarily mean a sick hamster. But, it’s crucial to keep an eye out for any signs of distress or discomfort.

Remember, your little furball relies on you for their health and happiness, so stay informed and keep them safe.

How to Keep Your Hamster Cool and Comfortable in Hot Weather

So, how do you prevent your hamster from overheating and ensure their comfort during hot weather? Here are some tips.

First off, consider relocating your hamster’s cage to a cooler area of your home.

Basements or bathrooms usually provide a more refreshing environment.

However, avoid placing their cage near direct sunlight or heat-generating appliances like stoves or fireplaces. Ideally, maintain the room temperature between 64°F (17°C) and 75°F (23°C).

Air circulation is another key aspect. A fan can help, but avoid pointing it directly at your hamster to prevent respiratory issues or skin dryness.

Next, evaluate the size and material of your hamster’s cage.

A Syrian hamster requires a minimum space of 0.05 m², whereas a dwarf hamster needs at least 0.03 m².

A larger cage aids in temperature regulation and ventilation. Metal, plastic, and glass cages are acceptable, but avoid wooden ones as they can act as a breeding ground for bacteria and they can chew on the wood.

Bedding is also vital. Opt for soft, absorbent, and hamster-friendly materials.

Avoid dusty, scented, or toxic substrates like cedar, pine, or corn cob. Paper-based products, such as Carefresh or Kaytee Clean & Cozy, are excellent choices.

Also, ensure there is enough bedding (at least 5 cm ≈ 2 inches ) for your hamster to burrow and nest comfortably.

Lastly, hydration is vital! Provide cool water for your hamster to drink and fresh fruits or vegetables for them to munch on twice or three times a week.

Also, try to limit handling your hamster during the hottest parts of the day.

Signs & Symptoms That Your Hamster is Overheating

Overheating can lead to heat stress, a potentially life-threatening condition where a hamster’s body temperature rises above the safe range.

This could result in dehydration, organ damage, and even death in severe cases.

Additionally, overheating can make hamsters more susceptible to infections, parasites, and diseases like the dreaded wet tail disease.

So, how can you tell if your hamster is too hot?

Look for signs such as panting, a bright red tongue, drooling, lethargy, loss of appetite, or unusual weight loss. They might also lie flat on their stomach or sleep in open or exposed areas.

Remember, every hamster is unique. If you notice any changes in their behavior, it’s always a good idea to check their body temperature. You can use a pet-friendly thermometer or even the back of your hand.

  • Thermometer Test: Gently press a pet-friendly thermometer against your hamster’s skin. A reading above 102°F (about 38.9°C) is a red flag, indicating your hamster may be overheating.
  • Quick Hand Test: This isn’t as exact as a thermometer, but placing the back of your hand on your hamster’s tummy can give a rough estimate. If their tummy feels unusually warm, it might be time to take action.

Can Hamsters Die from Overheating?

Indeed, overheating can turn fatal for your fluffy companion. Hamsters are small creatures, and even minor temperature changes can make them uncomfortable.

If not managed promptly, overheating can escalate into a serious health crisis.

Overheating isn’t a seasonal concern for hamsters. It can occur year-round due to various factors. Let’s delve into these:

  • Direct Sunlight: Hamsters are nocturnal, and accustomed to cool, dark burrows. Direct sunlight can elevate their body temperature quicker than you might think.
  • Lack of Shelter: Just as we seek air-conditioned rooms on a hot day, hamsters need a cool spot to relax. Without proper shade, they can overheat swiftly.
  • Inadequate Water Supply: Water is crucial in helping hamsters regulate body temperature. If their water supply runs dry, overheating becomes a real threat.
  • Excessive Exercise: Hamsters are energetic critters. However, too much playtime, especially in warm conditions, can lead to overheating.
  • Stress: Surprisingly, emotional stress can manifest as physical distress, leading to a rise in body temperature.


Hamsters do sweat, mainly through tiny sweat glands on their feet, but it’s often imperceptible due to their thick fur.

It’s crucial to keep hamsters in a suitable environment as they can be at risk of overheating.

Ensuring they have the right conditions, away from direct sunlight and with adequate hydration, is vital for their well-being.
