Is it okay to put pocket!Ruki, Shuu and Yui in the same cage? What would happen then?
Pocket!Yui is a friendly species, so she may approach them to get to know them better. She would want to be on good terms with her cagemates and she will assume that they will feel the same way. Pocket!Shu most likely will not acknowledge her attempt to begin a friendship, and blatantly ignore her, while pocket!Ruki on the other hand may become mildly annoyed over pocket!Yui’s naive assumption that they will all get along with each other. He may in turn cause her to second guess herself and should pocket!Yui should any kind of perceived insubordination against him, he would not hesitate to remind her of her status as nothing more than a pet for their owner. Pocket!Yui may thus feel sad and turn to pocket!Shu for comfort.
Pocket!Shu will try to take advantage of pocket!Yui and try to get her to do things for him that he doesn’t feel like doing himself, such as grooming and feeding himself. Since he and pocket!Ruki both share a laid-back personality, they won’t have much to complain about each other (although problems will arise if the owner does not bother to keep the cage clean, as pocket!Ruki prefers clean and spotless environment, or he will nag). The owner must make sure that they do not forget about pocket!Yui, as both these pocket vampires will take advantage of her kindness because pocket!Yui likes to please others, and she won’t have anything left for herself.
