Yes, I agree with the comment of Womanswork below: as someone who spends the majority of their time with eight companion animals, including a parrot, I can attest to the fact that they exhibit feelings of joy, sadness, insecurity, jealousy and envy, among a range of other emotions. And the best thing is, they don't hide these feelings; they're writ large for all to see, if in fact one is willing to see...it's so much better than the emotional dissembling of humans.
