- The mother beaver builds a special birthing den in her lodge, which is lined with soft materials like grass, leaves, and fur.
- The kits are born blind and helpless, and they weigh about 1 pound (0.5 kg).
- The mother beaver takes care of the kits by nursing them and keeping them warm.
- The kits start to swim and eat solid food when they are about 6 weeks old.
- They stay with their mother until they are about 2 years old, at which point they will leave the lodge and start their own families.
