When is it acceptible to write from an animal's POV?

[Susan]

Can you suspend your disbelief if an author writes from a parrot's POV?  That's what Michael Chabron did in The Final Solution. The Final Solution

The entire book is not written in parrot POV, only one scene, but when I read it, I totally believed it. Comments on other books written in "animal POV?"  I know there's one written in a horse's POV, forget the title ...

It's never acceptible. It may, however, be acceptable, depending on the story. That said, I've never read a crime novel from an animal point of view that I could take seriously.

That's a bit contradictory, isn't it? Never acceptable ... it may however be acceptable?
