1. Clean with warm water and paper towels: First, gently wipe the hamster's anus with warm water and paper towels to help soften and clear the blocked stool. Make sure the water temperature is appropriate, and don't overheat or supercool, so as not to cause extra stimulation to hamsters.

2. Use olive oil or mineral oil: After wiping clean, you can lubricate the anus with some mineral oil or olive oil to help discharge the stool. Be careful not to use too much, so as not to overstimulate the hamster's anus.

3. Improve diet and environment: In order to avoid anal obstruction again, you need to improve the diet and environment of hamsters. Make sure to provide hamsters with enough water and cellulose-rich foods, such as fruits, vegetables and grains. In addition, dry sand or paper bed materials must be provided to reduce the influence of moisture on excreta and water.

If the above methods fail to alleviate your problem, or your hamster has other uncomfortable symptoms, it is recommended to consult a veterinarian for help in time. At the same time, please be patient and meticulous, take good care of your pet and let it feel your care and support.
