When Mimi has to go back to work after her maternity leave and Uncle Baudouin doesn't take the babysitting seriously, the kittens see the opportunity to get up to a lot of mischief. This puts the patience of turtle butler Ed to the test.
Everyone is excited about the exciting letter from Daddy from distant Africa. This makes Uncle Baudouin realize how much he misses his brother.
Ed has a day off and Uncle Baudouin thinks he will make good use of his niece Pippa who comes to visit. However, her butler qualities are not what he hoped it would be.
The kitties have wild fantasies about what they want to become when they grow up. However, 190 year old Ed already has the necessary work experience on many surprising fronts.
When Pippa comes along, Django gets strange butterflies in his stomach. Butler Ed reminisces about days gone by with his ex-girlfriend.
Patrick is angry and decides to run away from home in the hope that everyone will miss him. This brings the necessary stress to Uncle Boudewijn; he had promised Mimi to guard the kittens with his life.
Butler Ed receives an unexpected visit from an old love. It puts him in a difficult situation; Will he stay with the kittens or will he go with his love?
Uncle Baudouin is nervous because he is having a date for the first time in his life. Butler Ed promises to help him, but things turn out differently than expected.
Django is sick, but because he cannot sit still, the cold spreads quickly. Even butler Ed has a lot to do, while he has to take care of everyone.
Django tries to impress Pippa with fake stories. In the meantime, Uncle Baudouin is doing everything he can not to lose his chess match against butler Ed.
Party on Kattenlaan 9; it's the kittens' birthday! It is celebrated exuberantly, except by Uncle Baudouin who tries to drown his broken heart.
Peace at last! Uncle Baudouin thinks. The kittens and Mimi go to Papa in Dubai. Butler Ed is less happy with it, but gets a new friend
In order to maintain its luxury lifestyle, Uncle Boudewijn is forced to rent the upper floor to the beautiful, single Cathelijne. But is Cathelijne as honest as she looks? And what does she carry in her large, heavy suitcase?
The kittens are hungry, but fortunately café 'De kom' opens its doors today and barfish Annie has provided delicious snacks. Hopefully they will not be caught by Boudewijn, because he already has a hard time even without illegal kittens in his house.
Boudewijn's bank account is still empty. Strange, because Cathelijne says she just transferred the rent. There are strange noises coming from the attic floor. Ed does not really trust it. The pest control comes to examine the house and the kittens just manage to escape.
Ed is welcoming the very first bed and breakfast guest for Boudewijn: Isabelle, vine snail and snail artist. Mandarin suffers from heights, but Hugo has a brilliant plan to overcome it. Hope it turns out fine.
While Boudewijn is in the middle of a karma enema, he catches Hugo and Mandarin in his living room. He leaves Cathelijne and the kittens on the street without mercy. But Hugo would not be Hugo if he would just let that happen.
It is blazing hot on the Kattenlaan, Mandarin is afraid that he will melt. Boudewijn regrets that he has let Cathelijne and the kittens stay and is getting annoyed by the talkative rabbit Maurice, who is on honeymoon by himself to get over his animal shelter past and learn to love himself.
Today there is a talent show in café 'De kom'. Ed gives Mandarin singing lessons and Luna wonders if she also has talent. The swinging stick-insect Flang is already convinced that he will win, but then he does not know Hugo and Boudewijn yet.
The long-haired guinea pig Gilles is a guest at the bed and breakfast. He is afraid of friction and is rather scary. The kittens find him scary at first, but then discover that a sensitive guinea pig is hidden under his frightening exterior.
It is autumn and Boudewijn is getting very melancholy from all those falling leaves. In the bed & breakfast, the overstrained police officer Wolfgang is a guest with his beloved plushy Onnepon, which to his great horror disappears at a certain moment. Ed also turns out to be missing stuff and Luna has not been seen anywhere for ages, what would have happened?
Unexpectedly Ed's brother Nico is at the door and Ed is not so happy about it. Ed has to cook a big dinner for Boudewijn and leave Nico alone in his house, but whether that is such a good idea?
It has been snowing and the entire Kattenlaan is white. The kittens have never seen anything so beautiful. At Boudewijn the bailiff is standing on the sidewalk, he still has one day to pay his debts, otherwise they'll be booted out. Ed and Boudewijn organize a 'garage sale', hopefully the proceeds from the sale of Boudewijns beautiful things will be enough to pay the debts.
It is Christmas and Boudewijn is really looking forward to celebrating it on his own with a huge meal. Santa brings presents to everyone, except Boudewijn, who can not understand why he is being skipped ...
It is New Year's Eve and the kittens are convinced that they can stay up until twelve o'clock. Boudewijn is eagerly awaiting the results of the Keiharde Knakenloterij. He follows the advice of Ada, the clairvoyant mussel, and gives one of his lottery tickets to Ed. Moments later Fancy Fred of the Keiharde Knakenloterij is at the door, but who is he there for?
