Your hamsters' health: what to look out for

Hamsters are generally healthy animals and can live up to age of three. Until then, there are a few things to look out for when it comes to their health to ensure they live a fulfilling life.

Hamsters may be small, but there are a lot of things to look out for to make sure they’re in tip top condition. This useful guide lists the main things you need to look out for, including parasites, tumours, and dental health.

Remember, most illnesses come with age, so until they reach two years of age, you should be able to enjoy your hamster and everything they do. With any pet, we recommend you finding a vet who specialises in a certain species, like hamsters and small mammals. This will ensure your hamster gets the best possible care should they need treatment.

What to do if your hamster is losing fur

It’s quite common for hamsters, Syrian hamsters in particular to carry certain parasites, especially fur mites.

Incorrect bedding is one of the most common causes of fur mites. However, in some cases, your hamster may be suffering from hormonal changes or tumours, which may cause hair loss that appears to be symmetrical.

Consult your vet if your hamster is showing any of these signs of a parasite infestation:

  • Hair loss
  • Red, irritated skin
  • Severe dandruff
  • Small scratches all over their body
  • Visible lice or mites which look like orange or black dots within the fur

Wet tail

Wet tail is often brought on by stress – like change in their surroundings or the presence of another animal in your hamster’s environment. A build-up of bacteria in the cage can also cause wet tail, so regular cleaning is very important. Symptoms of wet tail include:

  • Watery diarrhoea
  • Lethargy
  • Loss of appetite & sudden weight loss
  • A very strong smell of faeces

Wet tail can prove fatal within days, and unfortunately doesn’t respond well to treatment. If you suspect your hamster has wet tail, take them to your vet as soon as possible.

Tumours

Tumours are fairly common in an elderly hamster. They can grow very quickly because hamsters have a fast metabolic rate. Mammary tumours are the most common and are the most likely to be cancerous.

When you handle your hamster – and you should do this regularly – check for unusual lumps and bumps on their body. If you’re at all concerned, take your hamster to the vet.

Nails and old age

As your hamster gets older, their nails will start to grow rather rapidly. Placing items like fruit tree wood for them to climb on can help file their nails down. However, your vet will be able to trim their nails if you don’t feel confident.

When your hamster reaches around two and a half years of age, you will start to notice a few common changes, including:

  • Overgrown nails
  • Hair loss, leaving sparse bald patches
  • Sleeping more
  • Drinking more
  • Lumps and bumps
  • Weight loss, but teeth remain in good condition

Becoming wobbly when walking about. Always keep an eye on your hamster if they’re housed in a mesh cage. Elderly hamsters can get caught in the bars if their nails have grown.

If you feel your hamsters are starting to struggle with one or more of these symptoms, talk to your vet. While they’re perfectly natural, you’ll want to make sure they’re comfortable and not in pain.

Dental health

Your hamster’s teeth will continually grow, so make sure you provide them with a varied diet and plenty of things they can gnaw on, including safe fruit tree twigs.

Occasionally, hamsters can suffer with overgrown incisors (the front teeth). This is more common in hamsters that have been bred poorly or have been involved in an accident where they may have fallen with an impact.

Hamsters who chew their cage bars regularly can also be at risk of dental damage so it is important to make every effort to discourage it. They easiest way is to provide a very spacious cage with lots of varied enrichment including tunnels, fruit tree twigs and toys to chew, suitably sized wheels and scatter feeding. Changing the environment regularly will also help to keep them interested.

Regularly check your hamster’s teeth to make sure they remain a good length. They should be a light yellow colour, although they can be white when they’re very young. For more information, see our article on ‘how to look after your rodent’s teeth’.
