This is a bit long and rambling, but bear with me if you care to.
I was just thinking about this topic, but in terms of videos instead of books. My children have discovered the Backyardigans. We are very picky when it comes to the shows our kids watch and at first glance, I wasn't a fan of the type of animation, but I have to admit, the show is growing on me.
Anyway, I was wondering why the characters are animals and not humans, and all I could come up with is the creators thought it would be cuter that way.
Now, tonight, I was reading a book to my daughters and the characters were animals (think Frog and Toad, but not nearly as good) and again, I found myself wondering why the characters were animals and not humans. They didn't have any "animally" characteristics. Yet, my kids really like the story. One thing that struck me was that having animals as the main characters allows authors and publishers to have adult characters (characters that live by themselves and do more adult things...like cook and clean and make decisions for themselves) while sidestepping the whole "kids don't like books with adult main characters" thing.
So, for example in "A Visitor for Bear" (which I love), a child couldn't live alone, making breakfast and tea and a cozy fire. A grumpy adult human might not interest a child, but a grumpy adult bear does.
That may explain one of the functions of the talking animal in children's lit.
Which, of course, is not the case with the Backyardigans. But I have to say, Pablo the Penguin IS pretty cute and I'm always in favor of a talking, singing hippo. Maybe it's because of my fond childhood memories of Henrietta from the New Zoo Review. I guess kids like talking animals.
