So i got my pretty girl in the end of december and she has some cage aggression issues. She bites and runs away while in the cage or on her cage, but is a sweetheart most of the time out of her cage. I believe she was kept in her little cage for at least 2 years without coming out to play so maybe thats why she is being mean? She also hisses when in her cage (or when the cat is around...?) but not really any other times. She does hiss at the budgie when he tries to play (i think he is trying to preen her, but she does not approve that or he is chewing on her feathers) They just met 2 days ago so i think its understandable that she doesnt trust him yet. He loves her though. He will try to kiss her and loves her cage even though its the tiny one lol. I hope to eventually let them both live in his giant cage, but idk (its roughly 4ft by 2ft by 3ft, but that is a bit bigger the inches arent even) any tips on getting her to be better about being calm in the cage?
