The Shattered Earth

"The Shattered Earth", takes place after a global catastrophe decimates over 90 percent of the world's population and transmutes the remaining humans into something other entirely.
One of the heroes in this story is half cat and the other is half bird... Talk about an odd couple...
Their quest leads them through many twists and perils as they seek to uncover the cause of these unimaginable end times and leads them to a possible cure. Many characters are introduced throughout, each with their own reasons for being worthy allies or opponents.
I've categorized this as Science Fiction, but it is very much a combination of that and Fantasy as well as Paranormal, Adventure and Anthropomorphic!
Side note: The paranormal is referring to the Gaia Virus that is attacking the spirits of the Earth
