Blue cat cartoons have a weirdly comforting power over me.
I don’t know if it’s the color blue, the cat shape, or the fact that half of these characters look like they’ve survived a lifetime of slapstick injuries and still showed up for another episode.
But whenever I see a blue cartoon cat, I instantly think: childhood TV, Saturday mornings, cereal bowls, and absolutely zero concern for realistic animal colors.
And honestly? Good. I’m not here for biological accuracy. I’m here for a blue cat getting hit with a frying pan and somehow still making rent in my memory.
Famous Blue Cat Cartoons With Names and Pictures
For this list, I’m looking at famous blue cat cartoons with names and pictures — the ones that are recognizable, nostalgic, meme-friendly, or just too strange to ignore.
Some are classic slapstick cats. Some are gentle kids’ show cats. Some are anime sidekicks. And one or two look like they were designed during a very energetic brainstorming meeting.
How I picked these blue cat cartoon characters:
- Icon factor: I wanted cats people can recognize from one image.
- Real popularity: These characters show up in memes, merch, reboots, kids’ shows, and nostalgia lists.
- Variety: I included classic cartoons, anime blue cats, educational shows, and modern weirdness.
- Personality: Being blue is fun, but being memorable matters more.
8Tom (Tom and Jerry)
Why he’s iconic: Probably the most famous blue-gray cat in animation history.
Comedy style: Classic slapstick, dramatic reactions, and endless failure.
My take: Tom loses constantly and still somehow feels like the main character. Inspirational, honestly.
Tom is the blueprint for blue cartoon cats.
He is determined, dramatic, emotional, petty, clever, unlucky, and somehow still convinced his next Jerry-catching plan will finally work.
It will not. But I admire the optimism.
Tom works because he is both the villain and the victim. One minute he’s plotting against Jerry, and the next he’s flattened into the shape of a household object. That is range.
If you’ve ever wondered whether Tom and Jerry are secretly friends or just lifelong enemies with excellent timing, I went deeper on it here: are Tom and Jerry best friends?.
7Doraemon (Doraemon)
Vibe: Blue robot cat with an entire sci-fi toolbox.
Signature detail: A gadget pocket for basically every childhood problem.
My take: Doraemon feels like the comfort-show version of a superhero.
Doraemon is one of the biggest blue cat cartoon characters from childhood for viewers around the world, especially across Japan and Asia.
He has such a simple formula, and it never really gets old: Nobita has a problem, Doraemon pulls out a futuristic gadget, things go wrong, and everyone learns a lesson after creating unnecessary chaos.
Classic.
I like Doraemon because he feels helpful without being smug. He’s gentle, patient, and usually trying to do the right thing, even when the gadget solution becomes a tiny disaster with buttons.
6Pete the Cat (Pete the Cat)
Best for: Blue cat cartoons for kids.
Main message: Stay cool, stay kind, keep going.
My take: Pete is the blue cat I’d put on when everyone needs to calm down, including me.
Pete the Cat is the chillest blue cat on this list, which makes him a necessary counterbalance to all the slapstick trauma.
He’s friendly, musical, groovy, and built around the idea that things can go wrong without ruining your whole day.
Imagine emotional regulation, but with whiskers.
Pete works because his vibe is consistent. He’s optimistic without being annoying, gentle without being boring, and kid-friendly without making me feel like my brain has been wrapped in bubble wrap.
If you’re building a general animation watch list, not just a cat-specific one, my bigger hub is here: cartoons and anime to watch.
5Happy (Fairy Tail)
Signature detail: A blue cat with wings.
Role: Comic relief, loyal sidekick, and occasional emotional support missile.
My take: Happy proves a cute mascot can still matter to the story.
Happy is one of the most famous blue anime cat characters, and he’s instantly recognizable even if someone only knows Fairy Tail in passing.
He’s small, cheerful, loyal, and perfectly designed to lighten the mood right before the plot decides to throw furniture at everyone emotionally.
What I like about Happy is that he isn’t just decoration. He jokes, reacts, supports the team, and then suddenly helps at exactly the right moment.
Also, a blue flying cat is just a strong design choice. No notes.
4Gumball Watterson (The Amazing World of Gumball)
Style: Mixed media, surreal comedy, and constant visual jokes.
Theme: School life, family chaos, and bad decisions with confidence.
My take: Gumball is what happens when a blue cat cartoon breaks every cartoon rule on purpose.
Gumball Watterson is the modern blue cat chaos gremlin.
He’s sarcastic, emotional, impulsive, funny, and usually one tiny decision away from turning a normal day into a full-blown Elmore incident.
Gumball works because the show feels like the internet learned how to animate. Fast jokes, strange visuals, absurd escalation, and enough style shifts to make a traditional cartoon blink twice.
He’s a blue cat, yes, but he’s also a walking bad idea with a school backpack.
3Oggy (Oggy and the Cockroaches)
Core gag: Blue cat vs. three roaches forever.
Comedy style: Slapstick, quick pacing, and Tom-and-Jerry-style frustration.
My take: Oggy is pure frustration comedy, and somehow that makes him lovable.
Oggy is basically slapstick stress in blue cat form.
He wants peace. He wants snacks. He wants a normal day. Unfortunately, he lives with cockroaches who treat his house like a theme park for property damage.
Relatable? Maybe not. Emotionally understandable? Absolutely.
Oggy works because the premise is simple and endless. Blue cat tries to relax. Roaches ruin everything. Chaos escalates. Repeat until I start feeling bad for the furniture.
2Blanket (Cats and Peachtopia)
Movie: Cats and Peachtopia, also known as Cats.
Setup: A sheltered city cat pushed into a bigger adventure.
My take: I like Blanket because he’s a dad cat story, not just comedy chaos.
Blanket is a little different from the more famous blue cat cartoon characters on this list.
He is not really a slapstick icon or a loud comedy mascot. His story leans more into family, fear, growth, and the idea of leaving a safe little world for something bigger.
That makes him stand out. Sometimes a blue cat does not need to chase a mouse, fight roaches, or pull gadgets out of nowhere. Sometimes he just needs emotional baggage and a journey.
1Cat (Peg + Cat)
Best for: Blue cat cartoons for kids.
Hook: Math adventures that are actually gentle and fun.
My take: This is one of the few learning cartoons I can watch without feeling like I’m being talked down to.
Cat from Peg + Cat is an indigo-blue sidekick who helps Peg solve problems, usually by staying calmer than she is.
That alone makes him valuable. I too would like a small blue friend who appears during stressful math situations and prevents me from dramatically spiraling.
If you’re looking for safe, gentle blue cat cartoons for kids, Cat is one of the cleanest picks here.
My Picks for the Most Recognizable Blue Cat Cartoons
If I had to narrow this whole blue-cat universe down to the most recognizable names, I’d pick these first:
- Tom — the classic. The blueprint. The king of animated failure.
- Doraemon — global icon status with a gadget pocket.
- Gumball — modern meme-era blue cat energy.
- Oggy — slapstick frustration that never clocks out.
- Pete the Cat — the calm one, thankfully.
What I like about blue cartoon cats is that the color makes them feel instantly friendly, but the personalities can go in completely different directions.
Tom is dramatic. Doraemon is helpful. Pete is chill. Happy is loyal. Gumball is chaos. Oggy is exhausted. Blanket is emotional. Cat is educational without making me want to hide behind the couch.
One color, one animal, eight completely different vibes.
Final Thoughts
Blue cat cartoons have stuck around because they’re easy to recognize and weirdly easy to love.
Maybe it’s the friendly color. Maybe it’s the cat silhouette. Maybe it’s just that animation has trained me to accept blue cats as normal, while still questioning why I can’t find my keys.
Either way, I’m not complaining.
For me, the best blue cat cartoon characters are the ones where the design gets my attention, but the personality keeps me watching.
Now I’m curious: which famous blue cat cartoon did I miss?
