Bogo loves Luke and Daisy, but the feeling is not 100% mutual.  Bogo knows that he is a animal and that Luke and Daisy are too, therefore Bogo thinks that were they go is where he should go.  He is so small that he is able to to follow them anywhere and he just appears, they are not too found of that.  Daisy, she is a Mama and she would have loved to have babies of her own.  She takes good care of Bogo and lets him do pretty much whatever he wants to do.  Luke on the other hand is one calling the family meetings to have this crazy thing kicked out.  Luke is slowly learning to deal with Bogo, but  he is still keeping his eye on him.

Bogo thinks that he too should be in the cage.

Bogo loves to sleep on Daisy.
