Hamsters
Hamsters are omnivores with cheek pouches that can impact on sticky or sharp foods; their tiny body mass means even small toxic doses are significant.

Toxicology Profile
Extreme Body-Mass Sensitivity
At 25–130 g body weight, sub-gram quantities of toxic foods can deliver lethal concentrations. A single grape seed or citrus wedge contains enough sugar and acid to cause serious metabolic distress.
Cheek Pouch Retention
Sticky, acidic, or moist foods can become impacted inside cheek pouches, where they ferment and release toxins directly against the delicate mucosal lining, causing localized necrosis and systemic infection.
Diabetes Predisposition
Syrian and Russian hamsters are genetically prone to spontaneous diabetes mellitus. Sugary foods trigger rapid-onset hyperglycemia and can precipitate diabetic crisis even in young animals.

Clear FiltersSunflower Seeds
Sunflower seeds are a favourite hamster treat and safe in small amounts, but they are high in fat. Too many lead to obesity, and salted seeds should be avoided entirely.
Peanuts
Plain, unsalted peanuts are not toxic to hamsters, but their very high fat and calorie content makes them a food that demands strict portion control. Fed too generously or too often, peanuts contribute to obesity, fatty liver disease, and nutritional imbalance in a species already prone to metabolic problems. A single small peanut kernel once or twice a week is the ceiling for most adult hamsters.
