Tiny, active and curious, mice make excellent pets for families who can give these the attention and variation in environment they need. Mice love to play and to hide and build nests. They need to exercise as well, and most mice enjoy running on an exercise wheel. Wheels should be made of sturdy plastic or metal, and shouldn't have rungs that mice tails can get caught in. If your mouse is active on his wheel, it may develop a squeak. The wheel isn't broken, but the axis joint may need some lubrication.
Remove the wheel from your mouse's cage.
Clean the wheel well with soap and water.
Dry the wheel with paper towels.
Apply a few drops of the animal-safe lubricant at the point where the centre of the wheel attaches to the stand.
Spin the wheel a few times to distribute the lubricant.
Wipe away any excess lubricant using the paper towel.
Replace the wheel into your mouse's cage.
