One of the most iconic blue cats in animation is Tom from Tom & Jerry. But the more I thought about it, the more I realized blue cats show up everywhere—classic slapstick, kids’ TV, anime, and even modern streaming cartoons.
Whenever I see a blue cartoon cat, I instantly feel comfortable. Maybe it’s because blue characters tend to be designed as “safe,” friendly, and funny. Or maybe I’m just wired to associate blue cats with childhood TV, cereal, and cartoons playing way too early on a Saturday.
Either way, here are 8 of the most famous and popular blue cat cartoons—the ones I think almost everyone recognizes (or should).
Animated Blue Cat Cartoons
How I picked these blue cat cartoon characters
- Icon factor: You can recognize them from one image.
- Real popularity: These cats show up in memes, merch, reboots, and “remember this?” threads.
- Range: I included classic cartoons, kids shows, and a couple of anime blue cats.
8Tom (Tom & Jerry)
🐾 Why he’s iconic: Probably the most famous blue-ish cat in animation history
🎬 First era: Classic theatrical shorts (the originals still hold up)
🧠 My take: Tom is the rare character who loses constantly and still feels like the “main character.”
Tom is the blueprint for slapstick cartoon cats: determined, dramatic, and always convinced his next plan will finally work. If you’ve ever wondered whether Tom and Jerry are secretly friends (or just lifelong enemies), I went deep on it here: are Tom and Jerry best friends?
7Doraemon (Doraemon)
🤖 Vibe: A blue robot cat with an entire sci-fi toolbox
🎒 Signature: Gadgets for literally every childhood problem
🧠 My take: Doraemon feels like the “comfort show” version of a superhero—helpful, gentle, and always trying to do the right thing.
Doraemon is one of the biggest blue cat cartoons on the planet—especially in Japan and across Asia. He’s cute, instantly recognizable, and built around a simple formula that works forever: kid has a problem, Doraemon pulls out a gadget, chaos happens, lesson learned.
6Pete the Cat (Pete the Cat)
🎸 Best for: Blue cartoon cats for kids (wholesome, musical, easy watching)
🧠 Message: Stay cool, stay kind, keep going
🧠 My take: Pete is the blue cat you put on when you want your brain to relax.
Pete the Cat became a modern kids’ staple because the vibe is consistent: friendly, optimistic, and “everything is going to be okay.” If you’re building a general watch list for animation (not just cats), my bigger hub is here: cartoons and anime to watch.
5Happy (Fairy Tail)
🪽 Signature: A blue cat with wings (Exceed)
😂 Role: Comic relief + loyal sidekick
🧠 My take: Happy is proof that a “cute mascot” can still be essential to the team.
Happy is one of the most famous blue anime cat characters, and he’s instantly recognizable even to people who aren’t deep into Fairy Tail. He’s the kind of character who exists to lighten the mood… and then suddenly saves someone at the exact right moment.
4Gumball Watterson (The Amazing World of Gumball)
🎨 Style: Mixed media, surreal comedy, constant visual jokes
🏫 Theme: School life chaos + family nonsense
🧠 My take: Gumball is what happens when a blue cat cartoon decides to break every cartoon rule on purpose.
Gumball is the modern blue cat icon: sarcastic, emotional, and always one bad decision away from disaster. The show is also interesting historically because it helped normalize “internet humor pacing” in kids’ cartoons—fast cuts, random visual gags, and absurd escalation.
Fresh update: The series has also been revived as The Wonderfully Weird World of Gumball (a continuation/revival title), which makes Gumball one of the rare blue cat cartoon characters to get a modern streaming-era comeback.
3Oggy (Oggy and the Cockroaches)
🪳 Core gag: Blue cat vs. three roaches (forever losing)
🎬 Comedy style: Slapstick, quick pacing, “Tom & Jerry” energy
🧠 My take: Oggy is pure frustration comedy—and somehow that makes him lovable.
Oggy is basically the European cousin of classic slapstick: minimal dialogue, physical comedy, and endless escalation. If you like old-school “no words needed” cartoon humor, this one is a deep catalog.
2Blanket (Cats and Peachtopia)
🐾 Movie: Cats and Peachtopia (also known as Cats)
🌆 Setup: A city cat forced into an adventure
🧠 My take: I like this one because it’s a “dad cat” story—not just comedy chaos.
Blanket is a blue cat living a sheltered city life until he’s pushed into a bigger world. The story leans into family themes and the “search for paradise” idea, which makes him feel different from the purely comedic blue cats.
1Cat (Peg + Cat)
📺 Best for: Blue cartoon cats for kids (educational + gentle)
➗ Hook: Math adventures (yes, it’s actually fun)
🧠 My take: This is one of the few “learning” cartoons I can watch and not feel talked down to.
Cat from Peg + Cat is an indigo-blue sidekick who helps Peg solve problems—mostly by staying calm when Peg starts panicking. If you’re searching for “blue cat cartoons for kids” specifically, this is one of the cleanest, safest, most parent-approved picks on the list.
My Picks: The Most “Recognizable” Blue Cat Cartoons
- Tom — the classic. The blueprint.
- Doraemon — global icon status.
- Gumball — modern meme-era blue cat energy.
- Oggy — slapstick chaos that never ends.
Blue cartoon cat characters are proof that one simple design choice—a familiar cat silhouette plus a “friendly” color—can create a character that sticks for decades. If you’ve got a favorite blue cat I missed, tell me and I’ll add it to the next update.
