Kimberly from Catscratch, better known as Human Kimberly, is the sweet, unicorn-obsessed girl next door in this Nickelodeon cartoon. She is the one human the three cat brothers truly count as a real friend. First impressions matter, and Kimberly makes a great one.
She is warm, a little bit gullible, and endlessly kind in a show that is mostly about three rich cats causing chaos.
Introduced in the 2005 series, Kimberly was built as the friendly nine-year-old, well, eight-year-old, girl who lives next door to Mr. Blik, Gordon, and Waffle.
Her odd little friendship with a trio of wealthy talking cats is exactly what makes her stand out. It is also why she is worth a closer look.

Who Is Human Kimberly?
Catscratch was created by Doug TenNapel, the mind behind Earthworm Jim, and it ran on Nickelodeon from 2005 to 2007. The show follows three cat brothers who inherit a fortune, a mansion, a monster truck, and a butler named Hovis. Into all that madness walks Kimberly, and she quietly becomes the show’s emotional anchor.
Her whole job, story-wise, is balance. While the cats scheme, argue, and chase money, Kimberly’s innocence keeps the show grounded. She is the sweet counterpoint to their ego and chaos, and she often nudges them toward doing the right thing.
She may not be in a ton of episodes, but she leaves a mark whenever she shows up.
Quick profile:
- Aliases: “Human” Kimberly

Kimberly’s Friendship with the Cats
The best part of Kimberly’s character is her strange, sweet friendship with the Catscratch brothers. There is an obvious species gap here, but she does not care. She sees Mr. Blik, Gordon, and Waffle as dear friends, quirks and all, and she happily accepts their bizarre world without blinking.
Meet the cats: The Catscratch brothers are Mr. Blik, the greedy, power-hungry schemer, Gordon, the sweet romantic with a fake Scottish accent, and Waffle, the lovable dimwit who yells “Splee!” Kimberly is the calm human at the center of their nonsense.
That open-heartedness is kind of the point. Kimberly refuses to judge the cats for being greedy or weird, and she always looks for the good in them. She is also deeply nurturing, constantly caring for the brothers, standing up for them, and steering them through their messes.
In a lot of ways, she is their moral compass, quietly teaching them about loyalty and doing what is right.
Kimberly’s Personality
Kimberly is a bubbly, warm-hearted kid with one defining obsession: unicorns. She adores them, sings about them, and builds a good chunk of her personality around them. Even though the cats can be prickly, she brushes it off and cherishes them anyway, always spotting the softness under the fur.
She is not just sugar, though. Kimberly is a bit of a mood-swinger. She will absolutely flip from cheerful to fed up when the cats crash her plans, then bounce right back to happy. She hangs out with her three human friends, Kaitlin, Kaitlyn, and Charlotte, who pop by often enough to occasionally startle Gordon.
On top of all that, she has a real gift with animals.
She took the wounded Mr. Blik into her home to nurse him back to health, and she showed Waffle the same kindness after a falling rocketship flattened him.
Did you know? Kimberly loves unicorns so much she has her own theme song for them. In “Unicorn Club,” she happily sings “Prancy prance unicorn, fancy pants unicorn,” which is every bit as adorable as it sounds.
Who Voices Human Kimberly?
Kimberly is voiced by Liliana Mumy, a voice actress you have very likely heard before. She played Mertle Edmonds in the Lilo & Stitch franchise, and she is the daughter of actor Bill Mumy. She gives Kimberly a bright, sincere energy that makes all that optimism feel real instead of syrupy.
Mumy nails the many sides of the character, from her giddy excitement on adventures with the cats to her stubborn determination when things get tough.
That performance is a big reason Kimberly clicked with so many young viewers, giving them a relatable, upbeat figure to root for. In fact, she elevates what could have been a flat side character into someone memorable.
Gordon’s Crush on Kimberly
Here is one of the show’s running gags: Gordon has a massive crush on Kimberly, and she is completely, blissfully unaware of it. She treats him with pure friendly affection while he trips over himself trying to impress her, sometimes bending the truth to look like a hero.
The “Unicorn Club” episode sums them up perfectly. Kimberly gets really mad when Gordon lies about seeing a real unicorn. But the second he rescues her from Randall the bear, she forgives him and plants a grateful kiss on his head. She clearly cares for him deeply, too.
When her friends made fun of Gordon for his tiny tail, she jumped straight to his defense without a second thought.
The Sweet Innocence of Kimberly
Innocence is the core of who Kimberly is. Her trusting, good-hearted nature makes her the calm center of the Catscratch storm, and she constantly serves as a moral counterweight to the brothers’ scheming. She is forever encouraging them to be kinder and to think about someone other than themselves.
That innocence also shapes how she sees the whole world. Kimberly truly believes there is good in everyone, mischievous talking cats included. Her unshakable faith in her friends gives the show a warmth you do not always get in cartoons this chaotic. In my opinion, that is exactly why she works so well as a foil for the cats.
How Old Is Kimberly from Catscratch?
Kimberly is 8 years old, an elementary schooler through and through. You will sometimes see her listed as 9, because a couple of sources disagree, but most official descriptions, including Wikipedia, land on 8. Either way, she is a little kid, which makes her patience with three chaotic adult cats even more impressive.
Is Kimberly from Catscratch Mexican or Latina?
This question pops up a lot, and the honest answer is that the show never confirms it. Kimberly is what fans call “ambiguously brown,” meaning her skin is drawn a little darker but her background is never spelled out on screen. Some fan sites label her as Mexican-American or Latina, but that is fan interpretation, not official canon. Treat it as a maybe rather than a fact.

For parents curious about the show, Common Sense Media has a full content rundown, and you can dig into the series’ history over on its Wikipedia page.
Tyler’s take: Kimberly is the glue that keeps Catscratch from spinning off into pure chaos. She is proof that a show does not need a loud, gimmicky kid character to land. Sometimes a sincerely nice one who just wants everyone to get along is the most refreshing thing on screen.
That is my fact-checked breakdown of Kimberly from Catscratch, from her unicorn obsession to Gordon’s hopeless crush.
This kind-hearted kid is quietly one of the best cartoon characters Nickelodeon put out in the mid-2000s.
