This is not an illness but has been known to cause hamster owners some concern when first noticed. The Syrian Hamster has a spot on each hip rather like a mole and these are its scent glands and are perfectly normal. The hamster will rub its hip against the side of the cage, secreting its scent to mark its territory. The hip area surrounding the scent glands may appear sticky from time to time. They are more noticeable on males than females.
Very rarely a hamster's scent glands may become infected or blocked and the hip spot area may become sore and inflamed. In this instance veterinary advice should be sought.
