The friendliest hamster breeds include Dwarf hamsters, Fancy rats, Guinea pigs, Fat-tailed gerbils, Syrian hamsters, Campbell's Russian Dwarf hamsters, Pudding hamsters, and Winter White Russian Dwarf hamsters. These hamster breeds are suitable as pets due to their gentle temperaments and ease of care.

Dwarf Hamsters
Dwarf hamsters have a good temper and are easy to handle. Once they get used to you, they will be very affectionate. When keeping them, you need to prepare a spacious cage and cover it with a thick layer of wood shavings, which should be replaced regularly to avoid unpleasant odors. In terms of diet, in addition to hamster feed, you can also feed boiled chicken, hard-boiled eggs, or soft cheese once a week.
Fancy Rats
Fancy rats have an intelligence level equivalent to that of a three-year-old human and can respond simply to their owners' reactions. They don't like taking baths and prefer to clean themselves. For their diet, regular rat food is sufficient. Also, they like to eat mealworms, but they should be kept away from direct sunlight for extended periods.
Guinea Pigs
Guinea pigs have a gentle temperament, are clingy, and are suitable for daily care. A newly arrived guinea pig may be shy at first. After waiting for a while for it to get familiar with your smell, you can try feeding it to build a closer relationship.
Fat-tailed Gerbils
Fat-tailed gerbils have an adorable and cute appearance, produce less urine, and have a faint odor, making them suitable for people who are not very keen on frequent cleaning. When raising them, the environment needs to be kept dry to avoid humidity.
Syrian Hamsters
Syrian hamsters have a gentle temperament and are suitable for those who pursue a quiet life. Although they require enough space and an understanding of their somewhat "aloof" nature, they can become ideal pets in a suitable environment.
Campbell's Russian Dwarf Hamsters
Campbell's Russian Dwarf hamsters have a gentle temperament, are easy to get close to people, and have a strong ability to adapt to their environment. They don't need a particularly large activity space.
Pudding Hamsters
Pudding hamsters have a mild temperament and like to interact with their owners. Although they tend to gain weight easily, controlling their diet can prevent health problems.
Winter White Russian Dwarf Hamsters
Winter White Russian Dwarf hamsters have a gentle and affectionate nature. After proper training, they can get along very well with their owners.
