Signs/symptoms: Loose, watery stools, appears healthy otherwise

Causes: Too many greens, possible viral infection, parasites, breakdown of natural bacteria in digestive tract



1. Clean cages and equipment and change bedding daily

2. Remove or limit greens in diet until condition improves

3. Feed grass hay only until diarrhea is gone

4. Boil drinking water until diarrhea is gone

5. Give live-culture yogurt or acidophilus water (1/4 to 1/2 acidophilus capsule in 8 ounces water) by eyedropper or syringe without needle by mouth until diarrhea is gone

6. If above remedies are ineffective, feed rice water to dry, uncooked oatmeal or rice cereal. Give in small amounts and decrease the amount as stools return to normal


If your guinea pig still has diarrhea after 4 to 6 hours with the above treatments, try the following:


7. Give pediatric electrolyte-maintenance solution (such as Pedialyte) or Nop Stress in drinking bottle (8 ounces) next to regular drinking water bottle, to replace fluids lost from diarrhea

8. Give 1/4 teaspoon antidiarrhea medicine (such as Kaopectate) by spoon or eyedropper 3 to 4 times a day, decreasing dose as stool returns to normal. Or use Dry Tail, following instructions on package


If your guinea pig does not seem to be responding to the above treatment after 1 day, take it to your veterinarian. Take a sample of the guinea pig’s stool so the veterinarian can check for the parasites
