There certainly are plenty at animal shelters... We have a double yellow headed amazon going on 17. We got Romeo when he was around 1 year.

Seriously think about it. A lot of the old folks in my families are dying off and those stories are gone with them. Not that you’re checking out real soon.... Sorry about that
