How can cats sense pregnancy in humans?
So how can cats sense pregnancy before you know? Most likely, their refined sense of smell and their ability to detect the changes in your body temperature and in your movements, habits, and behavior during pregnancy clue them into what’s going on. Here’s how this might work.
Your body chemistry changes
Yes, it’s possible that cats can sense pregnancy even before you have early pregnancy signs. This is due to their excellent and refined sense of smell. During pregnancy, you experience profound changes in your hormonal levels, when your body begins producing more progesterone, estrogen and human chorionic gonadotropin (hCG) hormones. These changes in your hormonal levels can affect your personal scent. Thanks to their keen sense of smell, cats may detect these changes even before a pregnancy test can.
