Syrian Hamster — care sheet

Beginner. The most beginner-friendly hamster: the largest, slowest and easiest to tame. The only hard rules are the ones the pet shop breaks — a Syrian must live completely alone, and needs a far bigger cage with deeper bedding than the ones sold for it.

A good-quality complete pellet or a proper hamster seed/grain mix, reflecting their natural seeds, cereals and a little insect protein. Constant fresh water from an easy-to-drink sipper. Syrians are not among the diabetes-prone hamsters, but still keep sugary and fatty treats to a minimum.

Far bigger than the cages sold for them, with a solid floor (never wire mesh) and a deep layer of bedding to dig and tunnel. A large barred cage, or a big glass/plastic tank with a ventilated lid, works — add a dark nest box, deep substrate to burrow, and multiple hides, away from ultrasound sources like TVs and screens.

Strictly solitary — a Syrian must live completely alone for its whole life. They are highly territorial, and two together (even same-sex) leads to serious fighting, injury or death. There is no safe way to pair them; give each Syrian its own enclosure.

Keep indoors, warm and out of draughts and damp. If a hamster gets too cold it can slip into a hibernation-like torpor, which is dangerous because pet hamsters lack the reserves to survive it — warm a cold, stiff hamster gently, offer food and water, and call a vet if unsure.

A deep, generous layer of safe paper-based or similar bedding over a solid floor — deep enough to tunnel in — topped with plain paper nesting. Coarse sand makes a good bathing/digging spot. Never cotton-wool or fluffy strand bedding (it can be swallowed or trap limbs). Spot-clean often; do a full clean only once or twice a month, saving some scented bedding.

Nocturnal and very active, so give plenty of space plus a large, solid, axle-free wheel with a non-slip surface (a Syrian needs a big wheel — small ones bend the back). Add tunnels, sand to dig, and safe things to gnaw. Scatter-feeding suits their natural foraging and hoarding.

Self-grooming; a shallow sand bath keeps the coat clean, and long-haired Syrians benefit from gentle brushing to prevent matting. Provide gnaw items so the continuously-growing teeth wear down, and check cheek pouches and the rear end stay clean.

None needed on a good, varied hamster diet.

The largest pet hamster — about 13–18 cm (5–7 in) long and roughly 100–140 g, which is exactly what makes it the easiest to hold.

Typically 2–3 years as a pet.

See a small-animal or exotics vet if you notice: A wet, soiled or matted rear end with diarrhoea, low energy and loss of appetite — “wet tail” progresses fast and is often fatal; see a vet urgently; Not eating, weight loss, or a hunched, low-energy hamster; Rapid or laboured breathing, or a bluish tint to skin or gums (possible heart failure); Any lump or swelling, or overgrown front teeth; A hamster that is cold and stiff (torpor) — warm it gently and seek advice; Diarrhoea after any medication — some antibiotics are fatal to hamsters.
