What is this tool?
Estimates when a pregnant dog or cat is likely to deliver. Dogs typically whelp about 63 days after breeding (normal range roughly 58–68 days) and cats queen around 63–65 days (roughly 58–70). Counting from the mating date is inherently imprecise because conception timing varies, so the tool shows a typical date plus the full expected window and how many days along the pregnancy is today. A veterinarian can date the pregnancy far more accurately with an exam or ultrasound.
