Let’s continue with the matter of pregnancy in our companion animals. In last week’s column we listed the gestation periods (lengths of pregnancy) of many animals. However, as we mentioned, you must understand that these numbers, which were documented, are not cast in stone. Biology is not like mathematics.
In the latter 2+2 is always equal to 4 (the smart ones among us could argue that, even in this case, there are exceptions to the rule). In biology however, the gestation lengths can vary. In humans, you will know that although we speak of a 9-month pregnancy, women can give birth at 8½ months, 8¾ months, 9 ¼ months after conception.
