Mother's Day is all about celebrating the greatness of maternal love. But because there are enough paeans to human moms and their incredible acts of kindness and sacrifice, this year, we're celebrating moms from the animal kingdom. Not just any animal moms, though, these are cats and dogs who've adopted babies from a different species and treated them like their own.
From cats who've adopted wolves and pandas, to dogs who've nursed piglets and Bengal tigers, this slideshow is a testament to the utter blindness of a mother's love. Take a look at the stories below, let your heart melt and don't forget to call your mom!
