The newspaper Chi was playing on is replaced with a litter box.

Chi believes she understands why people say a certain word to her a lot.

Chi remembers her mother and tries to go out and find her.

Asleep after a long day, Chi has dreams and nightmares about her past.

Mr. Yamada worries that Chi doesn't have any toys.

Chi has a bundle of new toys, but doesn't know what to do with them.

Mr. Yamada is trying to work. Chi has other ideas.

After Mrs. Yamada frightens her, Chi dashes out of the apartment.

Chi discovers the world outside the apartment.

While Yohei searches for her outside, Chi has fun discovering the local park.

The park becomes lonely and scary at night.

It's time for Chi's health checkup, but how to smuggle her out?

The landlady nearly spots Chi, but Yohei's quick thinking saves the day.

Chi's first medical check-up is a traumatic experience.

Chi is afraid that Mr. Yamada wants to take her for another check-up, and won't come near him.

Chi wants to scratch something. Unfortunately, her objects of choice are very expensive.

Things are inexplicably boring around Chi's house, and dinner is unusually large... a conspiracy is afoot to help her become independent.

It's Chi's first day home alone, but Mr. Yamada is worried about her.

Chi learns that an apartment without humans in it isn't as delightful as it seemed.

Mrs. Yamada needs to take out the trash, but Chi clings to the bag. Mrs. Yamada distracts Chi with a ball, but while Mrs. Yamada is out, Chi climbs up to the window and is almost seen.

Mrs. Yamada takes away the books and boxes so Chi can't climb to the window. However, when Chi jumps, she's just a few inches short of reaching the windowsill.

Chi is able to jump up to the windowsill, so Mrs. Yamada closes the door to Mr. Yamada's workroom. This angers Chi. Mr. Yamada buys a stuffed animal.

When talking with some neighbors outside, Mrs. Yamada thinks they've seen Chi in the window. However, it was the stuffed animal that Mr. Yamada bought. So, they buy more stuffed animals to put on the windowsill so Chi blends in.

Chi searches for a delicious snack, then later eats Yohei's pancakes and finds them delicious.

Chi thinks that everything Yohei plays with is prey. So, Yohei tries to find things Chi will not like, but only makes Chi happier and then she rubs against Yohei's hand.

Chi becomes suspicious of how much fun Yohei and Dad are having fun in the bath, so she goes in to see what they are doing. After Yohei pours toys in the tub, Chi looks over them and wants to play but unfortunately falls into the tub.

Yohei and Chi are both annoying each other with their bad sleeping postures, then later sleep comfortably together.

While Chi and Yohei are playing in the sand box, a large black cat appears from behind the bushes. They run inside, but the black cat walks into their home.

The black cat appears again in the Yamada house and eats Chi's dinner while the others are away.

After eating Chi's dinner, the black cat picks her up and walks over to take her chew toy and Chi tries to protect it. Then the black cat decides to groom Chi's back and so Chi realizes the cat isn't as mean as it looks. And leaves once again into the bushes.

Everyone tells Dad about the large black cat at dinner.
