WHEELS
MINIMUM SIZE REQUIREMENTS

21cm for Dwarf Hamsters
28cm for Syrian Hamsters
Ensure your hamster runs with a level back and NOT with it’s head raised. An unsuitable wheel size can cause serious spinal damage to your hamster.
A saucer wheel can be used as an additional accessory but does NOT replace a standing wheel. Always ensure you hamster has access to an upright standing wheel for the majority of the time.
Avoid using wheels made of wire or mesh. Any wheel used should have a smooth, flat running surface with no rungs or ridges and a closed back wall.
Wire and mesh wheels cause cuts on your hamsters feet which can become inflamed and infected. This is called bumblefoot and it causes your hamster a lot of pain while walking or running.
Wooden wheels should be covered in a few coats of non-toxic varnish or paint to protect hem from urine stains. Wheels with balls bearings are extra silent.

PLASTIC VS WOODEN
PROS OF PLASTIC WHEELS
- Easy to clean
- Cheaper than wooden wheels
- More accessible (most wheels in pet stores are plastic)
- Some can be tightened if they become wobbly
CONS OF PLASTIC WHEELS
- Not ideal for big chewers, plastic should not be ingested
- Can break easier, generally lower quality than wooden wheels
- Not natural material
- Can be louder than wooden, as they generally don’t have ball bearings.
PROS OF WOODEN WHEELS
- Natural material, safe if chewed
- Smoother and quieter due to rigid structure
- Generally higher quality than plastic wheels, longer life
- Doesn’t bend or warp under the weight vof larger hamsters
CONS OF WOODEN WHEELS
- More expensive
- Solid structure and unexposed mechanism means the axle can’t be fixed if it breaks
- Absorb urine, can’t be deep cleaned (Wooden wheels can be coated with non-toxic paint/sealant to prevent wee from being absorbed)
- Cork running strip can be ripped up by destructive hamsters
UNSUITABLE WHEELS
Wire wheels:
Wire wheels can be very harmful to your hamster. Their limbs can fall between the prongs and become trapped and broken.

Mesh wheels:
These wheels can result in your hamster developing Bumblefoot – An infection of the feet due to reoccurring damage and inflammation, caused from running on mesh wheels.

Wheels with exposed axles:
If hamsters lose their footing while running on these wheels, they can become caught and pinched on the exposed axles. This can lead to broken limbs as well as serious injuries.

Dangerous running surfaces:
Not all proper sized hamster wheels are safe. For example, the American brand Silent Runner. They are correctly sized, but offer replaceable running tracks such as ones with holes to allow wee to escape and sand paper to keep your hamster’s nails filed down. Both of these running surfaces are dangerous and can cause bumblefoot and other injuries.
Wheels with “rungs” or exaggerated running surface grips can also be dangerous. There have been many people online who have reported their hamster’s feet bleeding from this wheel. As the wheel spins, the exaggerated bumps hit the hamster’s feet, causing injury. Prolonged used could cause bumblefoot.
THE EFFECTS OF SMALL WHEELS
But how does this occur?
The small amount of room a hamster has while using a wheel as small as the blue one in the video, doesn’t give the hamster enough room to move it’s legs properly. The hamster ends up compensating for this space and moving their legs in unnatural ways just to take a step forward. If a hamster is subjected to this for too long, it’s joints can become deformed.
