Beavers are incredibly loyal to their mates. Only case scenario in which a beaver changes its lifelong partner is in case of a death, than they find other mates. Male and female become reproductively mature at the same age, when they are around 3 years old, and that is when they choose their “soul mates”. They mate only in January and February, and a female carries a baby between 60 and 130 days.
