A whole animal universe is man-made, with shops, houses, technology etc. except that animals take the place of people. In some works, all kinds of animals take the place of people; all animals are human surrogates and considered equals to each other. In other works, some animals or types of animals take the place of people while others are considered normal animals. Sometimes, only one species of animal is a human surrogate. There are no humans in the setting, except a Token Human or two.
In some works where some animals or types of animals take the place of people and others are considered normal animals, there are both normal forms and human surrogate forms of one or more animal species.
Can involve Partially Civilized Animals, Civilized Animals, Funny Animals, and/or Petting Zoo People.

The world of ''Captain Carrot and His Amazing Zoo Crew!!," officially named "Earth-C" in the DC Comics multiverse system (post-Infinite Crisis, Earth-C was renamed "Earth-26"). Earth-C is designated as the world where most of DC's Golden and Silver Age funny-animal comics ("The Dodo and the Frog," "Peter Porkchops," etc.) take place.
Sir Hiss is still differentiated from a non-anthro animal. Anthropomorphic snakes are frequently depicted as slithering on their bottom half, while their head and some of their neck is constantly elevated. It's the closest to walking on two legs you can really pull off with a snake, so almost any anthropomorphized snake will move this way, while real snakes usually keep their head low to the ground while moving and put it up only briefly to analyze the surroundings or make a threat gesture.
Justified in the Saturday Night Live "Bear City" segments. A meteor crashed to earth, and the inhabitants of the town went underground in order to escape its effect. One of the unrealized effects was to make bears start acting like people (but they couldn't talk), taking the places of people in that society.
