furry utopia is about anthropomorphic animals that has taken over humanity, they took over when they weren't muted all the years back then. They speak english like humans but haven't seen humans before because has it's Been 2000 years ago. Also not only are the animals anthropomorphic, insects and other creatures(which weren't human) is now anthropomorphic. And they are all hman sized, so they will be 6 inch tall. Unless if they aren't. But anthros hate and fear humans.
