Cat has diarrhea, scooting, blood. When should I take her to vet?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | spayed | 3 years and 4 months old

My cat started having diarrhea yesterday which most likely happened do to new cat food (which she has tried before&didn't have any issue). Today, I decided to give her her old food because she continues to have diarrhea(wet&runny) & scoots same as yesterday. There aren't any other symptoms like vomiting, only that she has a smaller appetite. Right after pooping today at night, I noticed she has blood around her anus, there isn't any blood on her poop tho. Is this urgent? Should we go to the vet?

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Elsa and for providing a picture, it's very helpful. Poor girl, you are correct that a sudden change in diet can cause diarrhea. Continuing diarrhea as well as scooting can cause the anus to be quite irritated and that may be the cause of the blood. She sounds pretty uncomfortable if she is scooting, and she is also showing she feels badly if her appetite is low. Given she has had diarrhea for over 24 hours, I do think seeing the vet is best. I do not think it's an emergency, so do not rush her to an ER vet tonight unless she stops eating, stops drinking, starts vomiting, and/or becomes very lethargic. Wait until the morning and if she is still having diarrhea then, I'd have her see the vet. I hope this helps!

    Thanks for using Petco Pet Education Center, formerly Petcoach! Diarrhea can be observed with conditions such as colitis, gastroenteritis, dietary indiscretion, intestinal parasites, among many other possibilities. I recommend that you have Allie evaluated by your veterinarian for further assessment and treatment. They may choose to check for parasites and to start medications for diarrhea depending on the results. You can add 1 teaspoon of canned pumpkin to her meals which could help with mild cases of diarrhea though she should still go to see her veterinarian. Good luck! Hoping for a speedy recovery!
