Hemp or corn cob bedding: which should you choose for your rodent?
Hemp or corn cob bedding? For most rodents, hemp wins: soft, highly absorbent, virtually dust-free and well suited to digging. Corn cob still has its strengths, however, notably its absorbency in the toilet corner. This comparison complements our general guide to safe bedding and shavings.
What are the strengths of hemp bedding?
- Very low dust: ideal for the sensitive airways of hamsters, rats and gerbils.
- Soft and light: perfect for digging tunnels, on its own or mixed with hay.
- No aromatic oils: unlike softwood shavings, it irritates neither skin nor lungs.
- Price: 8 to 14 € for 30 to 40 litres, i.e. roughly 0.25 to 0.35 € per litre.
When is corn cob worth considering?
Corn cob (the ground core of the cob, not to be confused with corn pellets) absorbs urine remarkably well and locks in odours: it excels as a litter tray filler for rats and guinea pigs, or under a layer of hemp in strategic spots. Its round granules, however, are uncomfortable as a main substrate and cannot be dug through. Expect 10 to 15 € for 10 to 12 litres: pricier per litre, but you use very little.
Which bedding for which species?
Hamsters and gerbils in a tank: a thick layer of hemp or flax, mixed with hay so the tunnels hold. Rats: hemp on the cage floor, corn cob in the corner litter tray. Guinea pigs: hemp topped with a layer of hay, or washable fleece liners with corn cob in the toilet corner. Chinchillas: dust-extracted hemp only.
What pitfalls should you avoid when buying?
Steer clear of scented bedding (lavender, citrus), irritating for all rodents, and of poorly dust-extracted budget corn cob. If your animal sneezes, has watery eyes or scratches more after a bedding change, go back to the previous product and talk to an exotics vet if symptoms persist. All our comparisons are in the care and grooming category.
Frequently asked questions
Can you mix hemp and corn cob?
Yes, it is actually an effective combination: hemp as the general substrate, corn cob concentrated in the toilet corner to maximise absorption exactly where it is needed.
Is corn cob dangerous if swallowed?
Nibbled occasionally, it causes few problems, but keep an eye on committed bedding-chewers; massive ingestion can cause a blockage — consult an exotics vet.
How deep should the bedding be?
5 cm is enough for a rat or a guinea pig; 20 to 30 cm for a hamster or gerbils, which must be able to dig.
