Diet

• An unhealthy diet is often the cause of loose stools. Rabbits should be fed a balanced diet of hay, fresh vegetables and pellets, and it is important that they not be overfed.
  
  

Changes in Diet

• Hay and green leafy foods are an essential part of a rabbit's diet.Image by Flickr.com, courtesy of Jannes Pockele
  
  Adding green vegetables when a rabbit has not had them before can sometimes cause loose stools. Introducing the rabbit to hay first will help prepare his intestinal tract to accept green leafy foods.
  
  

Medicines

• Rabbits clean themselves almost continuously, swallowing a tremendous amount of hair. Some medications can prevent hairball problems but used in excess can cause loose stools.
  
  

Parasites

• Coccidia, a parasite that gets into a rabbit's small intestine, can cause diarrhea.
  
  

Foods and Medicines to Avoid

• Feeding sweet or salty snacks to a rabbit is not recommended. Penicillin should be avoided as it kills the good bacteria in the intestines. Diarrhea is a sign that the rabbit is not tolerating the antibiotic, and a different one should be tried.
