Is it normal for gliders to groom eachother? My gliders' cage is next to my bed room so I stopped by to play with them for a little bit before I went to bed. My boy, Nosy is really skittish so whenever I go near the cage he runs and hides on the top platform of the cage so I usually only get to interact with Bugsy, the girl. Today Nosy was apparetly getting used to me because he started truing to get closer to me, but when he did Bugsy would run over and just rub her face into all of his neck fur! I dont really know what this is but it looked kinda like grooming, the way cats do when they trust eachother. Of its not could someone explain this??
