Hamsters are literally one of the most adorable creatures. Everything about them just makes a lot of us fall in love. Hamsters are related to rats. Some even say they’re part of the Rat Family. If that’s the case, why not pet rats or mice? Let’s just settle things out logically. Domestic rats can be pets, but with their extra-large size and creepy tails, they often get people running away. Mice, on the other hand, are smaller but they still have weird, creepy tails. So, what’s left? Hamsters! Their chubbiness and fluffiness just adds extra cuteness to these adorable critters.
