A pasty stool can be from multiple things including parasites, inflammatory bowel disease, poor nutritional absorption, and more. I would first talk to your vet about bringing in a stool sample to test for parasites, giardia, and campylobacter. If everything is normal, you can try to put her on some oral probiotics to see if this helps to balance her stool. If not, I would have your vet do any exam and see if everything looks okay. They may suggest blood work and even a GI panel which tests for VitB12, folate, and 2 pancreatitic enzymes (PLI, TLI). I hope this helps!
