Hello im new to this site and I've adopted a gala who I've named grumpy , I've had him nearly 7 Months. I'm having some behavioral issues with him . He's been attacking people who get to close to either him or me. He has never once biten or showed any aggression towards me, it's the complete opposite he's very affectionate and cuddly. I'm concerned since he's made quite a few people bleed , especially people I live with . I need some advice for dealing with him I don't want him to be stuck in his cage all the time
