Delta Pavonis IV

Delta Pavonis IV is a planet where the local sapient life forms include anthropomorphic cats and dogs. By 2006 they had achieved a level of technology on par with 20th century Earth, with such amenities as cars and restaurants.
Delta Pavonis IV should not be mistaken for the planet Beast, whose local sapient life forms include rather different anthropomorphic cats and dogs.
