Have you ever seen an animal happier than this little piglet? Piglets may be adorable, but don't mistake them for unintelligent! They can recognize their mother's voice and know their name within two weeks. Believe it or not, mama pigs can even sing their babies to sleep while nursing! Amazing that humans aren't the only ones who do this.
