They are both extremely photogenic animals, shining under the glory of the digital camera. Perhaps they are deliberately putting on a charade for the camera, once they exit out of the limelight, they will turn into enemies once again, turning virile and fierce, swiping their sharp, pointy paws at each other.
This is how humans behave any way. When they see that the camera is watching, it makes sense for them to pretend to get along, once they get removed from under the watchful eye of a camera or an authoritative person, they devolve into violent outbursts and berating each other with vile language. Could these two animals be up to the same intentions? We can never find out unless we're able to contact the owner and learn first hand whether the two really do love each other.
