A cat Loki with a pair of distinctive fangs has quickly become one of the most famous felines on Instagram thanks to evil-looking face. Loki, who now has more than 23,000 followers online, was adopted from a cat shelter by her owner Kaet, who explained on in a posting that she knows very little about the cat’s distinctive appearance.
