Hamsters are burrowing animals which in the wild dig and inhabit tunnels which can range up to 70 cm (about 27.5 in) deep and several meters long. They contain multiple caves and tunnels connecting them to serve as sleeping den, toilet area and storage to house their large hoards. Hamsters have a natural urge to burrow and build these tunnels, closing off old ones and constructing new ones on a regular basis.
The hamsters we keep in our homes still have the same natural urges as their wild counterparts which is why we need to offer them a safe, stable substrate to be able to burrow in.
We recommend the following minimum depth to be added to the majority of the enclosure:
Syrian Hamsters – 30 cm or 12 in
Winter White, Campbell and Hybrid Dwarf hamsters – 20 cm or 8 in
Chinese Hamster – 25 cm or 10 in
Roborowski Dwarf Hamster – 15 cm or 6 in
More is always better! As already mentioned, hamsters a very avid burrowers and the more bedding offered, the more likely they’ll follow their natural urges and create intricate tunnel systems.
The following materials are safe to be used as a substrate in the majority of the enclosure:
Wood Shavings made from Aspen, Spruce or Birch trees
Unscented Paper Bedding
Hemp Bedding
Teabag Bedding (which is also hypoallergenic)
All hamsters require a sand bath where they’re able to dig and roll in. You can use a large dish or a box to hold it. It should have the following minimum sizes:
Syrian Hamsters – 30 cm or 12 in in diameter, with a sand height of at least 10 cm or 3.9 in
Winter White, Campbell and Hybrid Dwarf hamsters – 20 cm or 8 in, with a sand height of at least 5 cm or 1.9 in
Chinese Hamster – 25 cm or 10 in, with a sand height of at least 5 cm or 1.9 in
Roborowski Dwarf Hamster – At least 1/3 of the enclosure, with a sand height of at least 5 cm or 1.9 in
The following sands are recommended:
Chinchilla Sand, not to be confused with Chinchilla Dust!
Bathing Sand marketed towards hamsters or gerbils
Reptile Sand, both in yellow and red
Sand made from sepiolite or attapulgus are safe for the rodent. These clays are suspected to be cancerous when inhaled frequently, but hamsters do not live long enough for it to be an issue for them. It only can be problematic to the owner if they plan on caring for rodents for several years. Wearing a mask and good ventilation when pouring it is recommended.
