Did you know that in 1996, there was a raging debate over whether or not the guinea pig belongs in the rodent category? After all, the guinea pig cousin, the rock hyrax is said to be related to the elephant!

And although they may not be directly related to their wide mouthed mammalian water-loving hippo cousins, some skinny piggies certainly could fit right in as the tiniest of hippo lookalikes! #wheekwheekforhippos <br><br>Read about the hot rodent debate by clicking the picture below!
