Pumas can mate at anytime of year. In order to attract a male puma, a female leaves a special smell on the ground. She also screams loudly to attract males. Pumas mate usually in late winter and early spring. Most litters in the United States are born between April and September. Both males and females become sexually mature by the age of two years. Males and females only come together to mate, after mating, the male leaves. Two to three kittens are born after three months period. When the puma kittens are born, they are blind. They usually weight just over one pound and are about 12 inches long. Puma kittens have large spots on their fur, and rings on their tail. The kittens drink their mothers milk to grow big and strong. The mom raises the kittens on her own.
