You probably remember the bright red hair. It was impossible to miss. If you spent any time on Nickelodeon during the early 2010s, that specific shade of "Red Velvet Cupcake" was burned into your retinas. But for those asking who played cat in sam and cat, the answer is a name that has since become one of the biggest forces in global pop music: Ariana Grande.
It's weird to think about now.
Before the sold-out stadiums, the Grammy awards, and the "Positions" era, Ariana was a teen idol playing a ditzy, high-pitched character named Cat Valentine. She wasn't just a sidekick anymore. By the time Sam & Cat premiered in 2013, she was co-headlining her own show alongside Jennette McCurdy. It was a massive moment for Nickelodeon, but for Ariana, it was also the beginning of the end of her life as a child star.
The Evolution of Cat Valentine
Ariana Grande didn't actually start as Cat on this specific show. To understand her role, you have to go back to Victorious. Dan Schneider, the creator behind many Nick hits, cast her as the bubbly, somewhat dim-witted friend of Tori Vega. Cat was eccentric. She'd get distracted by shiny objects and talk in a voice that sat about three octaves higher than Ariana's natural speaking tone.
Honestly, the transition to Sam & Cat was a gamble. Spin-offs are notoriously hit or miss. The premise was simple enough: Sam Puckett (from iCarly) and Cat Valentine (from Victorious) become unlikely roommates and start a babysitting business. It was basically a collision of two massive fandoms.
Ariana had to maintain that specific persona—the wide-eyed innocence and the constant "dimness"—while her real-life career was starting to explode in a very different direction. While Cat was worried about bibble and fuzzy hats, Ariana was recording "The Way" with Mac Miller. The contrast was jarring. You had a rising R&B star wearing floral skirts and talking like a toddler on camera during the day, then hitting the recording studio at night to belt out Mariah Carey-style riffs.
Why the Red Hair Mattered
The hair wasn't just a fashion choice. It was a contractual obligation that nearly ruined Ariana's natural locks. Because the show's creator didn't want a cast full of brunettes, Ariana had to bleach and dye her hair bright red every other week for years.

"It completely destroyed my hair," she famously shared on social media years later. This is actually why she became so well-known for her signature high ponytail. It wasn't just a "look"—it was a necessity to hide the breakage and damage caused by the constant dyeing required for the character of Cat Valentine. When people ask who played cat in sam and cat, they often forget the physical toll that role took on the actress behind the scenes.
The Dynamics on Set
The show was a massive hit right out of the gate. Kids loved the slapstick humor. But behind the scenes, things were getting complicated. Ariana Grande was no longer just a "Nickelodeon girl." She was becoming a superstar.
Rumors of a rift between Ariana and Jennette McCurdy started to swirl almost immediately. Jennette later opened up in her memoir, I'm Glad My Mom Died, about the frustrations she felt. She mentioned how Ariana would frequently miss filming to go perform at award shows or record music, while Jennette was stuck on set. It created a weird power dynamic.
You had two very talented young women at different points in their careers. Jennette was essentially done with the child star life, feeling burnt out and resentful of the industry. Ariana was just launching into the stratosphere. It’s no surprise the show only lasted one season despite its massive ratings. It was a pressure cooker.
The Cancelation Mystery
A lot of people think Sam & Cat was canceled because it wasn't popular. That's totally wrong. It was one of the highest-rated shows on the network at the time. The real reason it ended after 35 episodes was a mix of salary disputes, the growing tension between the leads, and Ariana's music career becoming too big to manage alongside a grueling TV schedule.
Nickelodeon officially put the show on hiatus in early 2014, and by July, it was officially dead. Ariana posted a long, heartfelt note thanking the fans and the network, but she notably didn't mention her co-star in the initial draft of that goodbye. It was a messy end to a character that had been a staple of the network for nearly half a decade.

Life After Cat Valentine
Once the show ended, Ariana Grande wasted no time shedding the "Cat" image. She released My Everything and suddenly, the red hair was gone. The high-pitched voice was relegated to old clips on YouTube. She transitioned into a sophisticated pop icon faster than almost any other child star in history.
But she didn't just leave Cat behind; she evolved the platform.
Most people who grew up watching her still have a soft spot for the character. Even though Cat Valentine was often the butt of the joke, Ariana brought a certain vulnerability to her. It wasn't just "dumb blonde" tropes (well, red-head tropes). There was a sweetness there that felt genuine.
What to Remember About the Role
If you're revisiting the show today, it's fascinating to watch Ariana’s performance. You can see the glimpses of the powerhouse she’d become. Even in the silly musical numbers on the show, her vocal control was light-years ahead of what you usually see in teen sitcoms.
- The Voice: Ariana used a "character voice" that was much higher than her own.
- The Hair: That red was iconic but required a grueling maintenance schedule.
- The Wardrobe: Cat’s style was very "sweetheart," a stark contrast to the streetwear-heavy style Ariana adopted later.
- The Legacy: Sam & Cat remains a cult favorite, bridging the gap between the mid-2000s "golden age" of Nick and the modern era.
For those curious about who played cat in sam and cat, it’s a reminder that everyone starts somewhere. For Ariana, that "somewhere" involved a lot of hair dye and a very eccentric babysitting business.
Moving Forward: How to Revisit the Series
If you want to catch up on the show or see Ariana’s early work, the best way is through streaming services like Paramount+ or Netflix, depending on your region. It’s a fun time capsule. Watching it through the lens of knowing she becomes a global titan makes the humor hit differently.

You can also look for the "behind the scenes" stories shared by the cast in recent years. Jennette McCurdy’s book is the most honest account of what that era was actually like, providing a necessary counter-perspective to the glossy, bright world we saw on screen.
For fans of Ariana's music, listening to her debut album Yours Truly while watching Sam & Cat episodes shows just how hard she was working during that 2013-2014 window. She was essentially living two lives at once.
The most important takeaway is recognizing the talent it took to play a character so distinct from herself. Ariana Grande wasn't just a girl who got lucky; she was a trained theater actress who put in the work, even when that work meant dyeing her hair until it fell out. That kind of dedication is exactly why she's still relevant today while so many other teen stars have faded away.
Check out the early episodes of Victorious first if you want the full character arc. It makes the transition to the spin-off much more satisfying. You'll see the subtle changes in how the writers handled the character as Ariana’s real-world fame grew.
Actionable Insight: To truly appreciate the performance, compare an episode of Sam & Cat with a clip from Ariana's Sweetener world tour. The vocal contrast and stage presence evolution is a masterclass in career rebranding. If you’re a fan of TV history, keep an eye on how Nickelodeon handles spin-offs today; they rarely capture the same "lightning in a bottle" energy that the Sam and Cat pairing managed to achieve, however briefly.
