Reasons for hamster neck hair loss:

1. Age. If your hamster is over 2 years old, hair loss on its neck is a very normal metabolic phenomenon and there is no need to worry too much.

2. Caused by wear and tear. When raising hamsters, if you choose to raise them in an iron cage, it will easily cause certain harm to the hamster. Intense activities will cause certain wear and tear, making the hamster prone to hair loss. You can choose a plastic cage with lighter material for breeding.

3. Caused by improper diet. If a hamster eats food with high protein content or high-calorie food, it will increase the burden on the hamster's kidneys, resulting in hair loss.

4. It may be that the nutrition of the hamster is imbalanced, and long-term malnutrition leads to hair loss.

5. The hamster’s neck is sensitive, and the hamster will constantly scratch it with its front paws, causing the hair to fall off. At this time, you should carefully observe the hamster's skin. If there is indeed dirt, you can give the hamster a bath. However, you must not use water for bathing, but use special bath sand. If your hamster has skin problems, treat the hamster's skin, such as wiping it with skin medicine.

How to deal with hamster neck hair loss:

1. Choose a cage with a lighter material. When raising hamsters, most people choose to use iron cages.

After discovery, the diet structure needs to be improved, feeding rat food as the staple food, and a small amount of vegetables and fruits to supplement nutrition.
