Hamsters are known for their soft, furry coats. There are a few things you can do to get your hamster's fur to shine. A healthy diet will help your hamster's fur grow strong and shiny. Bathing your hamster can help to remove dirt and oil from its fur, which can make it look dull. Brushing your hamster's fur regularly will help to remove dead hair and distribute natural oils throughout the coat, which can help to keep it shiny. A Hamster Shiny Hair Sticker.
