A star-crossed male Jaguar risks his life to find a mate. Leaving his wonderful homelands, dazed, he is ready to dazzle a female. Seeking to find a tree to relax on, the Black Jaguar uses his powerful paws to raise his nurtured body up to the top branch. Making sure to show-off. He gazes down across the horizon, a sly smile on his face. Then, a young female Jaguar spots the male Jaguar sitting reslestlly on the branch. She slowly trotts toward the tree. Leaning against the tree the female shifts her weight to one side, lifting a leg. Looking to leave an impression, she lets out a stream of urine. Joyfully the female leaves to rest in the distance, and lays in the shade. Minutes feel like hours as she gets uneasy from the pressure. Finally, the male leaps from the tree and vigorously spins from the smell of the urine as it catches his nose. This is love at first "smell".

On a fine day, when the clouds are crystal clear and dispersing with the wind, the grey wolf is ambling across the thick bushes and muddy land. Minding its own business, the grey wolf suddenly stops. He senses movement on the other side of the bush. Curiosity, the main reason for its attention, gets the wolf on the other side of the bush.

Eyes locked and the stationary body standing on the ground, the gray wolf gazes towards a female wolf’s playful sways/dance. As part of its nature, when it is attracted, the gray wolf also starts dancing in order to show that he is paying attention to her!

This is how gray wolves 'attract' eachother! .

The lion approaches the lioness.

In the middle of the Kalahari Desert, a lioness is outside enjoying the warmth of the blazing sun. During this time the lioness was going through her heat. Soon a male kalahari lion approaches, with their strong sense of smell they could sense a lioness during her heat. As the male lion it is his job to approach the lioness. Taking slow long strides towards the lioness luring the male lion to her. This is the first heat the lioness is going through out of seven, throughout the whole year.

Looking to mate he brushes against one of the females backs. Showing her his thick, long mane. The male is usually the one to find a partner. Once he finds her, he will stay with her for 3-4 days. The one and only requirement being the female must be going through heat. Without this factor the male lion will not stay with her and therefore not mate. The male lion can smell when the female is in heat. Using its powerful sense of smell and lion instinct he finds his mate. He stands close to her and does not leave her side. Only 4 years old the lion has found his partner, but not for long. This lion will have 7 different mates over the course of the year. But this female will be the first.

Both male and female rats can give off a mating call. Male rats can vocalize at 50 kHz and the sound that it gives off are believed to trigger mating actions in female rats, and when a female rat vocalizes they can strengthen the males mating reactions. Rat urine contains an abundance of MUPs - which can induce attraction and activate neurons in the females posterodorsal medial amygdala.
