Do Cats Bleed After Giving Birth?

Many cat owners feel anxious when they observe their queen—an adult female cat—having vaginal discharge or bleeding after kittening. Understanding what is normal, what is not, and what warrants urgent veterinary care is critical for any responsible pet parent.

What Is Normal Postpartum Bleeding?

It is normal for female cats to have a bloody or brownish vaginal discharge—known as lochia—for up to three days after giving birth. The discharge can vary in color from red to brown, and may persist for up to three weeks, although it typically ceases much sooner. Other birthing fluids may also be present within a few days post-delivery. This small amount of spotting is generally harmless and part of the recovery process.

  • Lochia is usually red, pink, or brown.
  • May last up to three days, sometimes longer (but should be fading).
  • Discharge reduces gradually; excessive or worsening bleeding is abnormal.
  • Birthing fluids (amniotic fluid, tissue remnants) are commonly seen the first day or two.

When Should You Worry About Postpartum Bleeding?

While minor discharge is expected, large amounts of blood, persistent bleeding after several days, or any sudden changes in the color and smell of the fluid may signal complications. Abnormal bleeding could be due to:

  • Retention of fetal membranes: Tissue or membranes left inside the uterus can lead to infection.
  • Uterine infection or trauma: Signs include foul-smelling or dark discharge, fever, lethargy.
  • Fluid buildup in the uterus: May cause swelling and discomfort.
  • An unborn kitten blocking the birth canal: A rare but critical emergency.
  • Vaginal tears/hemorrhage: Caused by large kittens or difficult labor; medical attention required.

If you notice more than a small amount of blood or spotting after a few days, or any abnormal symptoms, contact your vet immediately.

Abnormal Signs to Watch For

SignWhat It May Indicate
Profuse, fresh bleedingTrauma or hemorrhage, emergency
Deep-red, black, green, or foul-smelling dischargeInfection (metritis, pyometra)
Sudden lethargy or collapseSignificant blood loss, shock
Refusal to nurse or neglecting kittensIllness or severe discomfort
Abdominal swelling, painRetention of membranes/tissues, infection
Fever, dehydration, pale or red gumsSystemic infection

Contact a veterinarian immediately if any of these signs are present.

Emergency Conditions and Complications After Birth

Some conditions following the birth of kittens can be life-threatening to the mother and her litter. These emergencies require prompt veterinary intervention:

Retention of Fetal Membranes

Sometimes, not all fetal membranes are expelled after birth. Retained tissues rot within the uterus, causing pain, restlessness, and possibly a brownish discharge. The queen may refuse food, water, or ignore her kittens.

  • Signs: Discomfort, reluctance to nurse, brown discharge
  • Risks: Infection, uterine inflammation
  • Treatment: Veterinary care, antibiotics, possible surgery

Metritis & Endometritis

Metritis and endometritis refer to bacterial infections or inflammation of the uterus lining. These conditions typically arise within three days postpartum and most often result from:

  • Difficult birth
  • Prolonged labor
  • Obstetric manipulation
  • Retained placentas/fetuses
  • Infection post-abortion or non-sterile procedures
SymptomExplanation
Foul-smelling pus or blood dischargeIndicates bacterial infection
Swollen, dough-like abdomenFluid and infection in uterus
Fever and dark red gumsSystemic illness
Refusal to eat, neglect of kittensExtreme discomfort and illness
Dehydration and decreased milkBody cannot cope with infection
Depression, increased heart rateBacterial infection spreading

Metritis can progress quickly to septicemia (blood infection) or septic shock, which is lethal if untreated. Affected queens may need hospitalization, intravenous fluids, antibiotics, pain management, and in some cases spaying (removal of the uterus).

Other Major Postpartum Emergency Conditions

  • Hypocalcemia (milk fever): Rare but serious in cats. Signs include panting, tremors, seizures, staggering. Immediate veterinary attention is vital.
  • Mastitis: Infection and blockage of milk ducts. Teats become painful, hot, and swollen; queen may refuse to nurse. Requires antibiotics; kittens may need to be hand-fed.

Signs of Birth Difficulties

  • No birth of a kitten after one hour of deep straining.
  • Visible kitten in the birth canal for more than 10 minutes.
  • Constant flow of fresh blood during or after birth lasting 10 minutes or more.
  • Lethargy, abrupt fatigue, fever above 104°F (40°C) or below 97°F (36°C).
  • Labor ceases with agitation, anxiety, or weakness.
  • If more than three hours pass between kittens, call your vet immediately.

How to Care for Your Cat After Giving Birth

Most queens recover smoothly, but attentive observation and supportive care are crucial right after kittening. Here are vital steps to promote recovery:

  • Monitor vaginal discharge for color, amount, and smell.
  • Check temperature, appetite, general behavior.
  • Ensure mother is nursing and caring for kittens.
  • Provide clean bedding and a quiet, stress-free environment.
  • Offer fresh water and food; queens may need extra calories while nursing.
  • Gently check teats for signs of mastitis (pain, redness, swelling).
  • Vet check for abnormal discharge, fever, lethargy, or neglect of kittens.

When Should You Contact the Vet?

  • If abnormal discharge persists beyond three days, especially if dark, green, or foul-smelling.
  • Large amounts of blood after birth or bleeding that increases after the first 24 hours.
  • Signs of illness (depression, lack of appetite, fever, nursing refusal).
  • Abdominal pain, swelling, or signs of distress.
  • Any sudden, unexpected changes in the queen’s condition.

Prompt veterinary assistance can make the difference between recovery and severe complications.

How to Reduce the Risk of Complications

  • Schedule regular checkups during pregnancy with your vet.
  • Prepare a hygienic birthing environment.
  • Minimize stress and allow the queen uninterrupted labor where possible.
  • Keep birthing supplies (gloves, clean towels) on hand.
  • Avoid unnecessary handling of newborns during the first few days except as advised by your vet.
  • If breeding is not intended, spaying before sexual maturity prevents many postpartum issues, including pyometra.

Frequently Asked Questions

Q: How much vaginal bleeding is normal after my cat has kittens?

A: Minor vaginal spotting and lochia—pink, red, or brown discharge—is normal for up to three days post-birth. Anything more, especially if increasing, signals a problem.

Q: What does foul-smelling discharge mean?

A: Foul-smelling, dark, green, or black discharge typically indicates uterine infection (metritis) or retained tissue. Immediate veterinary evaluation is necessary.

Q: Is bleeding ever dangerous after birth?

A: Fresh, profuse bleeding, especially with weakness or collapse, is an emergency. It may result from birth canal tears, hemorrhage, or retained placenta—contact your vet urgently.

Q: My cat hasn’t passed all kittens but stopped labor. Should I worry?

A: Yes. If more than three hours pass between kittens, labor ceases, or distress develops, veterinary intervention is critical to prevent retained kittens or uterine rupture.

Q: Can kittens be harmed if their mother has a uterine infection?

A: Yes. In severe infection (metritis), milk production drops, and bacteria may be transmitted to kittens via nursing, so hand-raising may be necessary if antibiotics are prescribed.

Q: What can I do to help my cat recover after giving birth?

A: Provide fresh water, nutritious food, a quiet nest, and monitor for any abnormal symptoms. Routine vet checks are vital, especially if complications occur.

Key Takeaways for Postpartum Cat Care

  • Mild vaginal discharge for a few days is normal; large amounts or foul smells warrant attention.
  • Monitor for emergency signs: excessive bleeding, fever, neglect, or abdominal discomfort.
  • Retained fetal membranes, metritis, mastitis, and hypocalcemia are the most severe postpartum threats.
  • Veterinary intervention saves lives—don’t hesitate to seek care if in doubt.
  • Proper postnatal care—monitoring, hygiene, nutrition, and calm—supports safe recovery and kitten health.

Additional Resources

  • Consult your veterinarian for personalized advice on postpartum care.
  • Online vet services (such as PangoVet) offer urgent consultations if an in-person visit is difficult.
  • Reliable veterinary websites (PetMD, FirstVet, and WagWalking) provide detailed guides on birth and cat care.
