Which animal has a gestation period closest to one month?

Which animal has a gestation period closest to one month?

• A. Rats
• B. Rabbits
• C. Ferrets
• D. Cats

Answer: (B)

Understanding gestation length helps you compare how long pregnancy lasts across species in relation to a month (about 30 days). Rats complete gestation in roughly 21 days, which is much shorter than a month. Rabbits are about 30–31 days in gestation, lining up almost exactly with a calendar month. Ferrets gestate for about 41–42 days, a bit over a month and a half. Cats have longer pregnancies, around 58–65 days, close to two months. Because the rabbit’s gestation is closest to 30 days, it’s the best fit for “closest to one month.”
