A Cat Made a Company

Nobita wears Doraemon's "Timer" to school and sees Shizuka looking sullen. When Shizuka gets home from school, she tells Nobita she needs help, and Nobita decides to help her. It turns out four kittens have appeared outside Shizuka's house, but her mother won't let her keep them. Nobita wants to secretly keep the kittens, but his mother won't allow it. Nobita, Doraemon, Gian, and Suneo (He uses his laptop to create poster for the owner of the lost cat) also help find homes for the kittens. Some people say they don't like kittens. Others like kittens, but they live in an apartment. Doraemon sees an old man who hates cats, but his face looks like a mouse. Doraemon is scared and hides in a corner, even getting chased by a female cat lover who wants to cuddle and pet her cat every day. Nobita abandons the kittens, and a dog tries to eat them. When Nobita is at his wit's end, he is forced to return because the gadget expires. His mother, who has caught a glimpse of this scene, misunderstands it as a sign of disobedience and comes looking for him, only to find Nobita in the "Snail House." Doraemon, seeing this, comes up with a clever idea and uses his "Timer" to send the kitten to kill the mouse. The moment the mouse comes out, Doraemon screams. He then teams up with Nobita and Shizuka to start a "Mouse Extermination Company."
