They are called panthers of Love because they come from the banks of the river Amour (Hēilóngjiāng, "river of the black dragon") in China. The male and the female lived together for a long time. But for three years, because of the captivity breeding program, they no longer have the right to meet, because all sexual relations are forbidden to these panthers of Love. They can therefore only be seen separately. They sometimes show their indignation against this forced separation.
