Opposite social rules — and both mis-sold
Hamsters & gerbils
The two small pets the pet trade gets most wrong. Hamsters are solitary desert burrowers that need a far bigger cage than they’re sold; gerbils are clan animals that must live in company yet can dramatically fall out (“declanning”). Both want deep bedding to dig.

HamsterMesocricetus auratus / Phodopus spp.The classic first pet the pet shop gets most wrong — solitary, needs a far bigger cage than sold, and worth doing right.
Syrian HamsterMesocricetus auratusThe biggest, most handleable pet hamster — a beginner favourite that must live completely alone.
Roborovski HamsterPhodopus roborovskiiThe smallest, fastest hamster and the longest-lived — a fascinating watch-don’t-hold dwarf, not a cuddle pet.
Winter White HamsterPhodopus sungorusThe dwarf that turns white in winter — charming, but diabetes-prone, so a strict no-sugar diet is non-negotiable.
Campbell’s HamsterPhodopus campbelliThe Russian dwarf with the highest diabetes risk of the pet hamsters — a strict no-sugar diet and a little patience with nipping.
Chinese HamsterCricetulus griseusThe slim, long-tailed, mouse-like hamster — nervous but tameable, best kept alone, and illegal to keep in California.
GerbilMeriones unguiculatusThe busy desert digger — bonded for life in clans, endlessly burrowing, and prone to the drama of “declanning”.
Fat-Tailed GerbilPachyuromys duprasiA calm, docile desert gerbil with a club-shaped, fat-storing tail — insect-loving, happy alone, and a gentle change from the social Mongolian gerbil.
