My pregnant cat has diarrhea. Is it normal or should I see a vet?
It sounds like your cat has a case of colitis, or an inflammation of the colon, resulting in an increase in the volume and frequency of stools.
Colitis can be caused by many different things. Some of the more common causes include intestinal parasites (most likely in a pregnant cat), dietary indiscretion, food intolerance, irritable bowel disease, pancreatitis, a foreign body/blockage and viruses.
I would recommend taking your cat in to your vet to be examined. They will likely want to check a stool sample and may recommend some lab work, a dietary change, and/or antibiotics.
I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.
