My senior cat had bloody diarrhea. Does she need a vet visit?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 16 years and 5 months old | 12 lbs

My plump, 16 yr old cat with kidney deficiency has always had bowel issues. Usually, it's constipation but sometimes diarrhea. She receives fluids every 5 days. Friday she had 3 episodes of liquid diarrhea. She was absolutely fine afterwards in every way. However, I noticed that there were two dark droplets of blood in her stool. She is still fine and not having any issues with diarrhea. Her eating is normal, but finicky. She sees a vet every 6 months. Does she need to see a vet? Karli

I would monitor Button for now, and keep an eye on her feces. If you see blood again, then yes I would take her into a vet. Her GI tract could have become irritated with the diarrhea, causing the blood in the feces. Should it be a one off occurrence, and she is eating normally with no more diarrhea, she does not require a vet visit.

    Any time there is blood in the stool it is recommended to see a vet, especially at her age. At 6 pounds it will not take long before she is dehydrated. They can check a stool sample to check for parasite or an infection and do an ultrasound to see if there is inflammation from an inflammatory bowel or something more severe. The blood work will tell if she is dehydration or any organ problems. They can provide treatment to get her back to her feet the fastest .

    Some spotting of blood can be quite common following severe diarrhea/colitis and as long as all other signs are normal and there is no weight loss I would not be overly concerned - it should resolve over 7-10days. I would recommend a probiotic such as fortiflora/canikur to optimize gut balance and promote recovery

    Poor Rocky! This bloody stool could be caused by GI polyps, GI ulcers, cancer along the intestinal tract, intestinal parasites, or toxins among other causes. As long as he isn't vomiting, refusing to drink water, or very lethargic, it is fine to wait until tomorrow to bring him into the vet for an exam. He should see a vet for this, and I would make sure to take him in first thing in the morning.
