Roborovski dwarf hamsters or Robos tend to live the longest, with some living up to 3.5 years.

Meanwhile, Siberian dwarf hamsters and Campbell’s dwarf hamsters only live to be about 1.5 to 2 years old.

Wild hamsters tend to live longer than hamsters in captivity [1]. These hamsters can live up to 5 years old. This is likely related to their diet and activities in the wild.

Take a look at this video to know the average lifespan of a hamster:

When hamsters are born, there can be as many as twenty. Known as pups, these animals rely on their mothers for the first 3 to 4 weeks of life.

Once they are old enough, you should separate your hamsters into their enclosures, especially if you have Syrian hamsters, who tend to fight each other.

You can often leave other hamsters together as they like social groups, but you need to separate them by sex, or you could have many babies.

Hamsters tend to reach sexual maturity between 4 and 6 weeks old, so you’ll want to separate males and females early on.

Females should not get pregnant until they are at least ten weeks old, or they might have complications like stillborn pups.

As your hamster gets over a year old, he’s starting to reach middle and old age.

During this time, the likelihood of him developing a health issue increases, so be prepared to take him to the veterinarian.

Choose a cage with appropriate wire spacing, solid flooring, and good ventilation. If you have multiple hamsters, ensure your cage is spacious enough for all. Include tunnels, multiple levels, and a separate nesting area to enrich their environment.

Additional Tips for a Thriving Furry Friend

  • Regular cleaning of your hamster’s cage is essential for maintaining a healthy living environment. Remove soiled bedding and uneaten food daily, and thoroughly clean the cage at least once a week.
  • This will help prevent the buildup of harmful bacteria and unpleasant odors [3].
  • Keep your hamster’s stress levels low by providing a consistent daily routine, minimizing loud noises and sudden movements near their cage, and handling them gently [5].

Health Problems That Could Affect Their Lifespan

Your hamster can be affected by many different health issues, especially if left untreated, which may affect his lifespan.

Possible issues include tooth problems, skin infections, upper respiratory infections, and diarrhea.

Dental ProblemsHamster Showing Teeth

A common health issue in hamsters is an issue with their teeth. Your hamster’s teeth are constantly growing and can grow down through his chin if they are not worn down.

You can help prevent dental issues by providing your hamster with things to chew on, such as wooden blocks.

Some pet stores even sell non-toxic houses they can live in and chew on.

If your hamster starts to have dental issues, they need to see a veterinarian, who may trim their teeth back to the length they should be.

Skin infections can be caused by improperly maintained habitats, primarily if waste builds up in the cages.

Having too many hamsters together can also increase their risk of skin problems, especially wounds due to fighting.

If your cage has sharp points, your hamster might cut himself, especially while exploring the cage’s nooks and crannies.

Inspect the cage regularly when you clean it to ensure that there don’t appear to be any issues.

Respiratory Infections

Upper respiratory infections are common among hamsters, and symptoms can include nasal or eye discharge.

You might also note your hamster sneezing or coughing.

If you start noticing any of those respiratory signs, you must get your hamster to the vet. Left untreated, an upper respiratory infection can worsen issues such as pneumonia.

Hamsters are also prone to gastrointestinal or GI problems, which commonly cause diarrhea in your hamster. Causes include bacterial infections, viruses, stress, and dietary indiscretion.

If you feed your hamster too much fresh food or protein, he might develop diarrhea. Eating too many seeds can also cause this to occur.

If you notice your hamster’s stool getting soft, he must get to the veterinarian and be evaluated. If you don’t treat him, he can develop dehydration and worsen quickly.

When you take your hamster to be examined, your vet might put him on antibiotics to treat a bacterial infection.

These are often oral medications and may treat upper respiratory infections, skin issues, and bacterial overgrowths causing diarrhea.

You must give all medications as your vet has prescribed them. Not doing so can cause a relapse in your pet or cause them to get worse.

If you want your hamster to live a long, healthy life, their housing, diet, and exercise are closely linked to their longevity.
