Adaptation Displacement: That's right, there was a book. There was a book called Sagwa The Chinese Siamese Cat. It was actually written by none other than Amy Tan.
Angst? What Angst?: A number of times, especially from Mama and Baba, who are not at all alarmed at how sad Sheegwa is to be away from her siblings when she is mistaken for a princess, nor do we see their reaction when we learn she is to be taken from home to fulfill her royal duties. In a much later episode, they don't even put their work down when Sagwa runs off to get Dongwa off her back, merely chastising his carelessness while Sagwa is very nearly taken away by a family who mistook her for a stray. Especially remarkable as they are horrified when the Magistrate once nearly gave away one of their kittens to an Italian dignitary.
Dork Age: The final quarter is considered to lack the brilliance that the majority of the first 30 episodes had. Justified, however, as the writers likely hadn't had a break to refresh and come up with better ideas.
Ensemble Darkhorse: The alley cats, as well as the one shot characters. Ping Wing the pigeon and Feng the cat are pretty good examples.
Even Better Sequel: "How Sagwa Got Her Colors" is followed by "Sagwa's Lucky Bat", note which acts as a sequel due to both flashing back to before Sagwa got her markings an even more touching and well-written episode that truly shows The Power of Friendship between Sagwa and Fu-fu.
Fan Disservice: Any time the Foolish Magistrate appears in his underwear. As it is an undergown, it's a downplayed example, however.
Gonk: Let's just say that for some, Tai-Tai may be rather hard on the eyes.
Idiot Plot: Sheegwa is mistaken for a legendary princess due to a star-shaped birthmark on her coat, and is immediately showered with lavish praise and treated like a dignitary before it's discovered it was actually simply a patch of dirt on her fur. Nobody took the time to verify that it is real, or that the legend itself had any credence to it. Furthermore, Mama and Baba forbid her to play as she'll be expected to fulfill her new role as a figure of wisdom, even though she's just a kitten and would have been taken from home if the misunderstanding had not been uncovered.
"The Magistrate's New Clothes", though a somewhat justified case as it is taken directly from the original fable where everybody in the palace fails to understand that the invisible clothes are an obvious ruse.
Sagwa and Fu Fu get themselves into a world of trouble when they play around with a valuable medallion gifted from the Emperor himself. Nobody who comes into possession of the medallion thinks twice about using it to suit their own needs, instead of reporting to the palace of their chance find.
Tai-Tai impulsively banishes the swiftlets, the honey bees, and the silkworms over minor inconveniences around the palace without even considering the consequences of any of it, until after the damage is done. That said, how exactly did she successfully banish such creatures from the palace?
Moral Event Horizon: Tai-Tai crossed this when she kidnapped Tung, the Magistrate's cricket, and convinced the magistrate that Tung had died. And while by the end of the episode, the magistrate is still convinced that his cricket is dead, unaware that the new replacement cricket Tai-Tai supposedly found is actually Tung. And Tai-Tai gets away with it completely!
Narm: In one episode Sagwa neglects to write the rules needed for a boat race being held in the village due to problems with Baba, and the Magistrate refuses to carry on without them in hand. When urged to carry on he declares "No rules, no race!" Somehow, this one line prompts him to start a musical chant that prompts the boat riders to join in, with the entire village soon getting in on the fun.
In one episode, Tai-Tai talks about her father, and while not directly stated, it's pretty heavily implied that he passed away at some point. An online summary for the episode ever referred to him as her "dear, departed father".
The episode, ”Tung The Singing Cricket", does say that Tai-Tai found a dead cricket in the garden, however.
In "Sick Day", the story scene where Sagwa gets captured and has a scared reaction because of Sheegwa telling her that she didn't play with her. Throughout the episode, Sagwa is heard screaming in fear. There's something creepy about, hearing your favorite character, scream with fear, especially since, they rarely show fear, at all...
Of the Uncanny Valley kind, in the episode where Tai-Tai keeps Fu-Fu as her lucky bat...seeing Fu-Fu dressed in that robe (and later that hat). The fact that this episode wasn't on Youtube until 2016 probably makes it a nasty shock for long-time internet-introduced fans.
From both that episode and the aforementioned "On The Run", the idea of being restricted of your freedom.
The fact that at one time Sagwa's village was governed by the magistrate in a similarly cruel and restrictive manner as that seen in "On the Run" makes for quite a bit of Fridge Horror.
To some fan, the fact that Sagwa was almost (accidentally) taken away from her own family in "Sagwa The Stray". Doubles as Tear Jerker.
Periphery Demographic: While Nostalgia Filter has given it older audiences, it's also a show with a unique setting, good animation, score and writing, and well-written characters with good choices of voice actors.
So Bad, It's Good: Tung's singing. It's probably the worst singing you'll ever hear, yet it's such a hilarious sound, and he clearly enjoys doing it a ton, to the point that you can't help but like it in a way.
They Wasted a Perfectly Good Character: Tung, Fam, Haiyo, Ping-Wing, the other two daughters, Tai-Tai's bird...there are quite a few. Somewhat justified as the show only ran for 40 episodes and the writers still had time to do more with the characters if they had made more episodes.
Toy Ship: Fans often ship Sagwa with Fu-fu and Dongwa with Hun-Hun.
Also, in any flashback where we see the Miao family without their trademark markings, with the obvious exception of Sheegwa.
Values Dissonance: In one episode, the Magistrate is expecting the delivery of a prized pigeon gifted to him by the Emperor, whom Fu Fu befriends when she escapes her cage. The Reader chastises the wagon driver for taking so long with the delivery, not stopping to acknowledge that the man is clearly mute and trying to use explain his troubles with his body language.
Since Sheegwa is the youngest character in the show note aside from the baby panda that appeared once, who is the youngest character to ever appear in the show , it's logical that she is this quite a bit. The most notable examples are in "Princess Sheegwa", "Precious Gift", and "Sick Day".
Haiyo (the bird that Dongwa befriends in one episode) would end up like this when the alley cats make fun of him.
Baba Miao can be viewed as this, such as the episode where he comes to terms with aging.
He crosses into Jerkass Woobie territory too. In one episode, he punishes Dongwa by writing tons and tons of scrolls. Dongwa decides to ask Saga for help, which she accepts by tells him that she will not be doing that again only for the two to get scolded by their father (who goes as far as accusing Sagwa of helping Dongwa decieve him). Later in the episode, he starts having a nightmare/flashback showing a young Baba Miao with his grandfather scolding him about the same mistake that his son would later do. After the dream ends, he apologizes to Dongwa and tells him that he was a little too hard on him.
Ba-do after getting stung in episode 20.
Fam, as well. You definitely want to give him a hug when he tells Sagwa about how he and his family sometimes go hungry.
Sagwa herself in the first episode. She accidentally changes the Magistrate's rules and spends the entire day scared that he'll find out she did it and throw her family out on the street. And even though everything works out well, Mama Miao later says after telling the story how Sagwa "did something she shouldn't have." She is also this for similar reasons in "Sagwa's Good Deed".
