Nocturnal creatures and quite small – even by hamster standards – winter white hamsters are part of the Phodopu genus of the Cricetinae family. They are one of the smallest type of hamster and they are easily identified by their unusual markings. Their mellow temperaments and petite size have made them very popular pets; however, they are susceptible to many medical conditions. Other names for this type of hamster is the djungarian hamster, dwarf hamster, or Russian winter white hamster.
Hamsters that belong in this genus are roughly half the size of other hamsters at just 3-4 inches long (7-10 cm) long, and they have the unusual ability to change fur color as the seasons change. Winter white hamsters are typically gray most of the time, with a black stripe extending down their backs and furry feet. One variety, referred to as the winter white pearl, remains white year round with a permanent black stripe, black eyes, and grey ears. The other type is known as sapphire, and it has a light gray coat with a faint blue hue.
The most common type of hamster cage, the wire mesh cage, is not suitable for winter white hamsters. Because they are so small, they can escape through the gaps between the wires. The best way to ensure they will not escape is to put them into a cage with solid walls, such as an aquarium cage or even just a large plastic bin, for those who are on a budget. Despite winter whites being some of the friendliest hamsters, they are unsuitable for young children since their small size and quick movements can easily cause the child to lose track of it.
On the other hand, for older children they are a great pet due to the low level of maintenance required. One may feed them vegetables, feeds, grains, and commercial hamster food. Fresh water should be readily available to them via a bottle, and one should replace their bedding frequently to prevent odor and bacteria build-up. Pine wood or cedar shavings are dangerous for winter white hamsters because they can splinter and hurt the hamster’s feet. Furthermore, cedar can also have a reaction to urine, creating toxic fumes that can be fatal if the cage is not well ventilated.
Similar to other types of hamsters, female winter white hamsters come into heat roughly every few days. Their gestation period is very short at only 16 days, and the female usually has a little of around eight pups. Females will be ready to mate as quickly as one day after giving birth.
There are multiple medical problems winter white hamsters can suffer from. For example, genetic disorders caused by inbreeding or hybridizing are the most common issues for these rodents. They are also likely to have allergies, poor eyesight, infections, and diabetes. Even a healthy hamster has a very short life span, lasting no more than 2-3 years before their natural death.
