As a hamster passes the age of one year signs of old age may appear such as fur loss, some weight loss, drying of skin and a general slowing down, although many hamsters do not show signs of old age until much later.

If the hamster is becoming slower or is sleeping more than usual the amount of exercise and handling should be reduced and extra care may be needed to ensure your hamster is kept warm.

It is important to regularly check the hamster's teeth to ensure that they are not broken or overgrown which can cause problems with eating.

Any sign of illness should be quickly treated by a vet as an elderly hamster may deteriorate very quickly when ill.
