Why is my female cat bleeding with strange fluid? Is it serious?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | unspayed | 3 years and 6 months old | 6 lbs

My cat is bleeding for past 2 days. On first day her bleeding was continuous, runny & followed by some yellowish green mucus. 2nd day she bled little but it was thick and dark red. Today her bleeding is little and runny. This is 3rd that she is bleeding like this. This happen once in every 2-3 months and her bleeding stops after 3-4 days. She's behaving like a human kid, very tender and loving. Also her nipples are bright pink and she's continuously cleaning them. Her health is in good condition

I would be extremely concerned that Max has a pyometra, which is an infection of the uterus that is fatal without treatment. Cats do not bleed when they are in heat, and this is not normal. This is something that needs to be checked out by a vet immediately, please bring her into one now. Best of luck.

My female cat is bleeding from her vagina, not pregnant or in heat?

Vaginal bleeding in a non-cycling female is considered abnormal. If your cat is acting fine otherwise and does not appear to be in distress, this may be something that can wait until tomorrow. However, if you feel the vaginal bleeding is excessive (versus just a red discharge) enough to where blood loss is a true consideration, this is not something that should wait until morning. Hope this helps.

My cat is in heat and has dried blood near her vagina. Is it normal?

Cats do not bleed during their heat cycle which makes me thing the bleeding is unrelated to her being in heat. it could be due to a urinary infection for example, i would recommend taking her to your vet in order to get it checked and treated.

My unspayed cat is bleeding from her vulva after heat. Is this normal?

We do not normally see a bloody discharge in cats with heat cycles like we do in dogs. For this reason I would recommend an exam by your veterinarian. We could have blood coming from the reproductive tract from infection or a tumor, or we could have blood from the urinary tract which could be due to infection, inflammation, bladder stones, bladder tumors. The vet will do an exam and may recommend a urine test and an x-ray or ultrasound of the abdomen to help determine the cause of the blood.

My female cat has bleeding and creamy brown discharge. Is it serious?

I would be extremely concerned that Lola has a pyometra. This is a life threatening infection of the uterus that requires immediate veterinary treatment. It would cause a creamy brown mucus discharge. A pyo is fatal without treatment, so I would take Lola into a vet right away. The vet can do a physical exam, blood tests, a urinalysis, and x-rays to diagnose she does have a pyo. If she does, spaying her in part of the recommended treatment. Please take her into a vet now.

Unspayed cat bleeding bright red during heat. Is it an emergency?

This is probably not because she is in heat (cats usually do not bleed during their period), this looks like a severe urinary infection/bladder inflammation. you need to take her to the vet in order to get it treated ASAP.

Why is my female cat bleeding for 2 weeks, not in heat, but mated?

If Jerry was mated with last month, it is possible that she become pregnant and she is now experiencing a spontaneous abortion. This bleeding can also be a sign of a uterine infection called pyometra, or it could be due to a blood clotting disorder. I would have Jerry seen by a vet as soon as possible. Now that you've identified which cat is bleeding, the cause of the bleeding needs to be diagnosed so she can be treated. I would bring her into a vet right away.

Cat leaking fluid, bleeding, and restless: Is it an emergency?

This sounds like she may be in labour if she has not been neutered and requires urgent veterinary attention at this stage - an emergency c-section may be required. Other possibilities may be severe infection or prolapse which would also require treatment urgently before major blod loss
