When Too Much Gas Becomes a Problem

If your guinea pig starts farting a lot or looks bloated, it’s a red flag .

Common reasons for guinea pig gas:

  • Eating gassy vegetables (broccoli, cabbage, kale)
  • Sudden change in diet
  • Lack of movement or exercise
  • Spoiled veggies or wet pellets
  • Stress or low-quality hay

If your guinea pig looks swollen, stops eating, or sits hunched, see a vet immediately.
Gas buildup can turn serious quickly.
