Siberian cat Nimbus is well known on TikTok for his noisy antics. A very vocal kitty, fans often compare his sounds to a racecar or a “Purrari.” He’s also a bit of a spaz, known for unleashing some of the most epic zoomies you’ll ever see. And his favorite time to do both? In the middle of the night, of course!
In this clip, though, his mom surprises everyone by showing the dramatic difference between Nimbus’s “inside” and “outside” voices. He’s incredibly loud when he’s indoors, but once he steps outside, it’s a completely different story. Make sure your sound is on for this one, you won’t want to miss it!
We’ve watched and written about a ton of Nimbus’ videos, but if we’d seen this one without knowing it was him, we never would’ve guessed that the outside cat was the same one! Nimbus’ mom says in the caption, “He gets his indoor and outdoor voices mixed up.”
As a fan of his videos, we can confirm!

Commenters’ Funny Reactions to Nimbus’ Two Voices
Fans are so used to hearing race car Nimbus that many were surprised by his outside voice. @Brittany & Bruce shared, “Clearly the outside air is full of helium LOL!”
Commenter @cathrynmcgrigor pointed out, “Inside Demon – Outside Angel. Putting on a pure face for his public.” @Bowz added, “He has multiple personalities!”
We had to go back and listen again when @Jeno8080 shared, “Sounds like he’s saying ‘uh-oh’ at the beginning. Like ‘Uh-oh I’m a little baby, look at me, I’m so cute.’ LOL!” @Aeryon added, “Acting cute to be let inside, but then…”
@staceygre43 said what we were all thinking, “Nimbus, I’ve never seen your innocent side!”
SPCA Pet Insurance reminds us that not all meows are created equal. “Cats have a vocal range that can express excitement, frustration, and everything in between. Here are some common feline sounds and what they might mean:
Standard meow: This is your everyday “I want something” meow aka a short meow – but what do short meows mean? It’s medium-pitched and usually means they’re asking for food, attention, or a door to be opened.
Long, drawn-out meow: This one usually spells urgency or frustration. It might be the “why is dinner late?” meow or a sign that they’re trying to get your attention for something important.
High-pitched mewl: Often used as a greeting, this soft and high-pitched meow may come with head-butting or leg-rubbing, your cat’s way of giving you a warm welcome.
Repeated meows: A rapid series of meows can signal excitement, especially when your cat knows something good is about to happen (like playtime or kai).
Sudden, high-pitched meow: This usually indicates discomfort or surprise, like when they accidentally step on something sharp or get spooked.”
