Here’s a recommendation of the cutest hamster breeds synthesized from multiple sources, combining appearance and temperament:

I. High-Beauty Adorable Representatives
Pudding Hamster
Fur color is as tender yellow as cream pudding, with big shiny black eyes, naturally carrying a "dessert" attribute.
Gentle and quiet, easy to handle and interact with.
Milk Tea Hamster
Fur color is a light gray tone like pearl milk tea, with a soft gradient back line.
Lazy and dazed, its slow-reaction appearance resembles a moving "glutinous rice ball".
Winter White Hamster
Snow-white fur with a gray back line, and ruby eyes adding a mysterious touch.
Active and restless, a "snow white elf" fond of exploration.
II. Highly Interactive Healing Breeds
Syrian Hamster
Golden long fur with a soft touch, and a round body like a plush toy.
Affectionate by nature, it will actively climb onto hands to seek interaction.
Violet Hamster
Smoky gray fur with a purple sheen, a quiet and gentle "sleeping beauty".
Suitable for owners who enjoy observing static cuteness.
III. Special Charm Varieties
Roborovski Hamster
Miniature size (only 4–5cm), with white eyebrows like a little old man.
Agile and lively, like a rolling "fur ball" when on a running wheel.
Amber Hamster
Amber-colored fur paired with red eyes, featuring a striking color contrast.
Highly affectionate, it likes to stay close to hands and daze.
(Note: Albino breeds like the Snowball Hamster require attention to strong light sensitivity issues.)
