2. Parasites
If a hamster is infected with external parasites such as mites and fleas, it will lose a lot of hair. It is recommended that the hamster be dewormed immediately.

If the litter is not replaced for a long time, bacteria will breed, causing the hamster to suffer from skin diseases and hair loss. This situation requires timely medical treatment.

Hamsters have a relatively short life span. They will slowly enter the old age around the age of two, and will also experience severe hair loss.

If you only feed your hamster the food it likes, resulting in a lack of other nutrients, it will cause endocrine disorders and lead to hair loss. Hamsters should be fed a variety of foods to ensure a balanced nutritional intake.
