I'm subscribed to a channel called mash-upZone. They post videos that are so 'cuteness overloading' it's difficult to watch them. Proceed with caution before watching their montages.
Edit, whoops. Mixed up the links.
My grandpa used to have a pet raven flying and jumping around in the house,washing itself in the sink and cursing and talking to people.
Cute and smart companion it was.
