guinea pigs courtship
The typical courtship display for guinea pigs can be witnessed during mating. The male wags his rear end, quivers his body and makes sprightly hops. He also sprays urine on his female mate.

CautionGuinea Pigs can sometimes breed at the age, so if you don't have any plan to breed your cavies, it's better if you separate males from females when they don't need their mum anymore so there will be no unplanned litters.
