Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Tilly! Hormones can affect the body so is a possibility on why she has diarrhea though I would think that would have been occurring the entire heat cycle. The most common causes of diarrhea re: intestinal parasites, viral or bacterial infections, dietary indiscretion, pancreatitis, toxin ingestion, food allergy or intolerance or a reaction ti a new treat/food or human food. If the diarrhea is severe then I would fast her for 12-24 hours then re-start feeding with a bland diet of boiled chicken or hamburger with rice. Feed 1 cup per 20 lbs per day until 2 normal stools. You can also add a probiotic, I like Purina Fortiflora. If the diarrhea doesn't improve before the weekend I would have her seen. Good luck!
