1, spring is here, everything is revived, and the prairie is in the season of animal mating.

2. Competing for a spouse is a common thing in the animal kingdom. American moose have this kind of internal contest every March and April. The winning stag can possess all the females of the whole herd and mate with them heartily, while the losing stag can only leave the herd and wander around alone.

Turn your eyes to the distant Australian grassland, where the male kangaroo is showing his male charm. The female kangaroo is deeply attracted by the male kangaroo and shows her love to the male kangaroo. Hundreds of millions of kangaroos finally found their mother after a hard struggle! Soon after, a new little life was born!

4. The lioness in estrus will also leave her own smell as a sign. When the lion smells this attractive signal, he can know which lioness is in heat. This gesture is sometimes an expression of love and sometimes a symbol of rejection by the lion.

5. The gestation period of lions ranges from 105 days to 1 2 days, and a litter gives birth to1to 7 cubs. Like domestic cats, they are just born and can't see anything. They were weaned at six or seven months, and these little guys have been born for about six weeks. It is impossible to know who their father is. Their fathers are either black lions or golden lions, and cubs born in the same litter may have different fathers.
