When I watched this video I wondered what would happen if they were in the wild and they had not been spayed or neutered. Reports indicate that bobcats maintained in captivity show little interaction between males and females during non-reproductive periods. This applies to bobcats who have not been neutered or spayed. In fact, females were extremely vehement in repelling males that approach too closely. Of course, things change with the onset of oestrus whereupon the behaviour of females changes to include more pacing and more affectionate movements.
We can't expect to see that sort of thing happening in this video because they have both been fixed so it seems to me we are looking at two bobcats who may or may not become friends. The video indicates to me that these two could be friends although there are unsure and their initial encounters are defensive with a hint of something better to come once they get to know each other.
