Doraemon: Nobita's Cats and Dogs in Time

On an ordinary day, Nobita accidentally encounters a clever and cute puppy. The puppy was particularly attached to him, so Nobita had no choice but to ask Doraemon to adopt him. At the same time, more and more kittens and puppies were abandoned around, and the friends were worried. They could not even find a place for the little animals to live in the back mountain. In desperation, Nobita and the others took the small animals to the prehistoric era when even the dinosaurs were not yet born, and used the evolutionary degeneration gun to promote the evolution of the animals. The next day, the friends went to visit the small animals as agreed, but they encountered turbulence in the time and space tunnel. We have arrived at an era that is ten thousand thousand years older than the day before. At this time, the country of cats and dogs has become unprecedentedly prosperous, and they make friends like Xiaoba here. Soon it was learned that the earth would be hit by a meteorite, and a conspiracy was brewing within the Cat and Dog Kingdom. A new adventure begins... This film is a commemorative work for the 25th anniversary of Doraemon The Movie.
