Parrots
Neighbor had one. She got custody in the divorce. Her neighbor has a beagle named "Loren".
If the parrot got lonely sitting on the deck, she'd call for Loren. The damned beagle would run over, all excited, and the parrot would talk to it, delighted with the company.
Incredibly bright bird, knew all manner of tricks, finally decided it wanted to go with the other party, and got mean to my neighbor. I miss it.
