In the meantime, there are a few things you can do to help alleviate your guinea pig's bloating and make them more comfortable. First, try to encourage your guinea pig to drink water. This can help to flush out their system and relieve any constipation that may be contributing to the bloating.

Getting the diet right to prevent bloating

To prevent bloating in your guinea pig, it's important to feed them a balanced diet that includes plenty of hay, fresh vegetables, and a high-quality guinea pig pellet. Avoid feeding your guinea pig processed or sugary treats, and avoid overfeeding them, as this can lead to bloating and other health issues.
