🔍 Pregnancy Diagnosis in Queens (Cats) Using Ultrasonography 🐱🩺
Ultrasound is a safe, effective, and non-invasive tool for early pregnancy detection and fetal monitoring in queens.
📅 When to Scan:
Day 15–17 post-mating: Gestational sacs may be visible.
Day 21–25: Ideal window to confirm pregnancy.
Day 28+: Fetal heartbeat and development become clearly visible.
🧬 Ultrasound Findings by Days:
Day 15–17: Small, anechoic gestational sacs appear in uterus.
Day 20–25: Embryos visible; heartbeat detectable.
Day 30–35: Limb buds, spinal cord, and fetal movement observed.
Day 40+: Further fetal development, organs visible, harder to count fetuses due to overlap.
🖥️ Ultrasound Details:
Probe: 7.5–10 MHz microconvex or linear transducer.
Approach: Transabdominal.
Position: Dorsal or lateral recumbency.
Scan Time: ~10–15 minutes.
✅ Benefits:
Early confirmation of pregnancy
Monitoring of fetal viability and development
Differentiation from uterine diseases (e.g., pyometra)
⚠️ Limitations:
Not accurate for fetal counting (radiography is better after Day 42)
Small litter sizes or fetal resorption may affect diagnosis
Operator skill-dependent
Ultrasound remains the gold standard for early and safe pregnancy detection in feline reproductive practice. 🐾
