It sounds like your cat has a severe case of colitis, or an inflammation of the colon. Colitis can be caused by many different things. Some of the more common causes include intestinal parasites, dietary indiscretion, food intolerance, irritable bowel disease, pancreatitis, a foreign body/blockage and viruses. Since your cat has been ill for several days at this point I would recommend taking her in to the vet to be examined. She may need fluids to correct any dehydration, a fecal examination performed and antibiotics and/or probiotics to help the diarrhea clear up. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.
