A red panda (think raccoon) recently gave birth to two little cubs at a Chinese zoo. But while the crowd watched, it became clear to zoo staff that mama wasn't all that interested in being a mom. They managed to find a Chihuahua--a new mom herself--who was willing to nurse them. (Follow the link to see a photo of the surrogate dog.) Strangely, the Chihuahua has now rejected her own baby and the staff are hand feeding the pup. This situation practically begs the question: Why can't we leave nature alone? I mean, isn't it a little weird that we are intervening in what should be a natural process for two species, and yet, our "help" has caused both moms to reject their own babies?
