We can all agree that cats are very mysterious creatures, but one in particular has people stumped because of its unusual color.
Since 2014, an unnamed green cat (yes, a real-life green cat) has been roaming the streets of Varna, Bulgaria and it's peculiar look has turned it into an internet sensation.
Many of the town's residents and tourists assumed the worst and chalked-up the cat's eye-catching fur color to have been caused by someone playing a cruel prank. Some of them even created a Facebook group to catch the perpetrator.
Thankfully, the truth behind the Bulgarian feline's unnatural color is far less sinister.
So how did this kitty end up with its emerald-hued fur?
