We all know them: the sugary sweet videos of a first meeting between a newborn and a family pet. Yet a new hilarious TikTok video went very differently.

This kitty was not a fan of one little human hairball.

TikTok user caydencazier recently posted a viral video of a first meeting that went the total opposite way of what she'd imagined.

"We were so excited to introduce our newborn to our cat," the clip's voiceover says.

"But then this happened."

At first, everything begins quite harmlessly: Fefe the cat begins to survey baby Maeve, the new addition.

She slowly creeps around the car seat where the newborn is sleeping. The four-legged friend then carefully bends down to the infant's face and sniffs it curiously.

Then, the feline backs away rather quickly, hurrying around the house to get away from the scene.

Needless to say, "introducing our newborn to our cat didn’t go as planned," the TikToker wrote.

The camera then follows the furry friend to the bedroom, where the cat proceeds to vomit all over the floor.

The interaction has amused over 6.4 million TikTok viewers and counting.

"Are you kidding me?!" the cat's owner says in the video. "Really now? Are you serious?!"

"She's worried sick!" a second voice is heard guessing in the background.

Users have found Fefe's reaction quite amusing.

"She knew she just got replaced," one user summed up. "What a way to protest."

"I had the same reaction to my siblings - totally understandable," a TikToker sympathized.

"Cat said 0/10 return to sender," another joked.

"The cat probably smelt a full diaper," a TikToker suggested.

The cat's owners replied to the comment with a follow-up video, showing the cat sniffing a dirty diaper. Yet, it surprisngly didn't make the cat sick.

"Fefe passed the poopy diaper test," they wrote.

Guess it's just new babies that send her over the edge!
