An example of a perfect animal is a cat. It's the internet's mascot. Their combination of silliness and cuddliness makes them the epitome of animalistic excellence.
An example of a perfect couple is the union of Chrissy Teigen and John Legend. Seriously, they always look like they're having an amazing time.
And they have a perfect little baby. I mean seriously, just look at Luna chilling with her bulldog right here.
