What are baby beavers called? few people know


Beavers are the largest rodents in the world and also one of the cutest. Although bear-sized beavers once roamed North America, they have been overtaken by their smaller counterparts we know and love today. An adult beaver weighs an average of 16 to 32 kg, and a large beaver can measure, counting its 30 cm tail, 1.3 m. Some even weigh over 45 kg.

Considered engineers of nature who restore wetland habitat by building dams and cutting down trees, beavers are the epitome of hard work.

But do you know what a baby beaver is called?

Baby beavers are called kittens, or kittens for short. Cubs born in the spring are called “yearlings” when they reach the age of one year.

Among the animals belonging to the beaver family we find:

  • ferrets
  • Muskrats
  • rabbits
  • skunks
  • Squirrels
  • petting

The kittens will be raised by both parents in a semi-flooded dwelling called a hut, where up to three generations of siblings form a so-called colony. Female beavers can give birth to up to six cubs each year.

These workaholics are born with all their fur, open eyes and the very beginning of 25mm teeth. Kittens can even swim just 24 hours after birth, taking their first fearless steps out of the hut at around three to four weeks of age. However, they need help learning to dive, as they dangle in the water like corks.

After two or three years in the family home, the kittens leave the family cocoon to find a life partner and start their own family.


Called “ecosystem engineers,” beavers are constantly working to conserve, change, and improve their environment. Beavers are key species filling an ecological niche in which their individual habitat impact is greater than most organisms.

Beavers not only use trees as building material for their dams and lodges, but trees are also a source of food as beavers are one of the few mammals that can digest cellulose.

Beavers build dams up to 2 meters high by intertwining branches and tapping on mud to create an impenetrable barrier. The change in water flow creates large pools or ponds that are ideal for feeding a beaver colony.

By changing the course of rivers and streams, beavers can flood large areas of land.

When these semi-permeable structures are abandoned and eventually collapse, what is left of the once-flooded waterway becomes a very fertile pasture.

The accumulation of sediment and debris caused by dams also changes the chemistry of the environment: an increase in carbon and a decrease in nitrogen in the environment diversify the ecosystem. These newly created sources of standing water are also attracting new species to the area.

While beavers are no longer considered an endangered species, they are still threatened by deforestation and urbanization in their homelands. We must take care of them, because our relationship with the beavers is mutually beneficial!
