===Reproduction===
Male kangaroos will go around the mob checking the females’ [[cloaca]]. Many times, males are rejected by the females because of size if they are small. In other cases, if a larger male is checking a female out, she may just move away. Sometimes, when a male is checking out a female, the female will urinate for the male, who will sniff the urine. Some studies show that this ritual is for the male to see if the female kangaroo is receptive to him or not.

If the female is responsive to the male, she raises her tail and the male will follow her. Sometimes the kangaroos will scratch each other’s tails or the male will give the female a back rub before mating. When the female is ready to mate she will arch her tail.
