Cat Pregnancy Signs: How to Tell If Your Cat Is Expecting
Recognizing Feline Pregnancy
Cat gestation averages 63–67 days (~9 weeks). Signs appear progressively; not every queen shows all signs.
Timeline of Typical Signs
| Week | Physical/Behavioral Changes |
|---|
| 1–2 | Subtle; possible mild nausea, appetite dip, increased affection or withdrawal |
| 3 | "Pinking up": nipples enlarge, become rosy pink (first reliable sign) |
| 4–5 | Weight gain begins; abdomen palpably thicker (vet can feel fetuses ~day 20–25) |
| 5–6 | Obvious abdominal distension; mammary development |
| 6–7 | Fetal movement visible/palpable; appetite increases significantly |
| 7–9 | Nesting behavior (seeking quiet, arranging bedding); clear vulvar discharge near term |
Other Common Signs
- Increased sleep/lethargy (late pregnancy)
- Reduced activity/jumping
- Morning sickness (some queens, weeks 3–4)
- Behavioral shifts: more clingy or more solitary
Diagnostic Confirmation
- Palpation: Day 20–35 (experienced vet only; risk of harm if done roughly).
- Ultrasound: Day 21+ (heartbeats, viability, count estimate).
- Radiographs (X-ray): Day 45+ (fetal skeletons mineralized; accurate count).
- Relaxin blood test: Day 25+ (placental hormone; confirms pregnancy).
Prenatal Care
- High-quality kitten food from diagnosis (extra calories, protein, DHA).
- Deworming (safe protocols) — roundworms transmit to kittens.
- Vaccinate before breeding; avoid live vaccines during pregnancy.
- Prepare kittening box: quiet, warm, low sides, washable bedding.
- Know emergency vet contact for dystocia (prolonged straining >1 hr, >2 hrs between kittens, green discharge without kitten).
False Pregnancy (Pseudocyesis)
Non-pregnant queens can show nesting, mammary enlargement, even lactation 6–12 weeks post-estrus. Resolves spontaneously; vet can confirm with ultrasound.
Always confirm with a veterinarian before assuming pregnancy or planning care.
