My family and I got Oscar through one of my Mums friends.
The home he came from didn't spend too much time with him and they wanted him to go to a loving family who will.
Also he is mainly a companion for my Mum when she goes away in her camper van to different places in my state over here in Australia so she is not alone.
I know it's hard to trust a new pet with birds, so I'm trying my best so he can be outside as well as inside, but I have to supervise inside and outside, as my cat doesn't like him and they will fight.
I trust my cat with my birds, but not Oscar as he has most likely never been around chickens before.
