Cat Pregnancy Duration Week by Week Changes and Preparation Checklist

Intro summary Pregnancy is a normal life stage for unspayed females. This guide explains how long cat pregnancy typically lasts, what changes to expect week by week, and a clear prep list to make delivery safer and calmer. If you are new, a short checklist and clear principles help you support mom and newborns with confidence during cat pregnancy.

One sentence answer Most cats carry kittens about 63–65 days from conception; monitor behavior and prepare a quiet whelping area as the due window approaches during cat pregnancy.

Core principles

• Keep the environment calm and predictable; stress can disrupt nursing and recovery.
• Provide balanced nutrition and steady hydration; changes should be gradual and monitored.
• Make a vet relationship early; plan at least one prenatal check to confirm due date.
• Prioritize safety: secure windows, remove toxic plants, and block small hazards.

New owner 14 day checklist Day 14 before expected delivery start preparing the space and routine. Choose a quiet box or low-sided crate lined with soft, washable bedding in a low-traffic room. Place food and water nearby but not next to the litter area. Ensure the litter box is clean and easy to climb into.

Week −2 to −1: practice short quiet times in the whelping area so the mother feels safe. Keep noise down and children supervised. Monitor eating and water intake twice daily and note any sudden drops. Keep a scale to record weight every 2–3 days; steady near-term weight loss is uncommon.

Supplies to gather: clean towels, disposable gloves, a digital thermometer, a heating pad (with thermostat) for emergencies, and phone numbers for your vet and emergency clinic. Have clean scissors and dental floss or sterile string available in case you need to assist the umbilicus, but only use if instructed by a vet.

Routine steps from easy to harder:

1. Set up the whelping box and bedding (easy).
2. Place food and water stations, and add a second litter box (easy).
3. Schedule a prenatal check and discuss delivery scenarios (moderate).
4. Prepare transport options for emergencies and practice handling gently (moderate).
5. Learn basic signs of labor and prepare to call your vet if complications arise (harder).

During the final days, watch for nesting, restlessness, and reduced appetite. Track temperature once daily near the expected date; a drop often precedes active labor. Keep your checklist visible and your phone charged.

Common mistakes and fixes

• Mistake → Leaving the whelping area open; Fix → Provide a secure, private box with one exit.
• Mistake → Changing food suddenly; Fix → Introduce diet changes over 3–5 days.
• Mistake → Overhandling newborns; Fix → Limit contact to mother-led introductions.
• Mistake → Waiting too long to call the vet; Fix → Contact early if labor stalls or heavy bleeding appears during cat pregnancy.

When to consult a vet Contact your vet immediately for any of these: labor longer than 24 hours without a kitten, strong contractions for more than 2–3 hours with no progress, heavy bleeding, green or foul-smelling discharge before kittens arrive, mother is collapsed or unresponsive, prolonged refusal to eat >24 hours, repeated vomiting or severe diarrhea. Also call if newborns are cold, pale, or not nursing.
