The video shared by TikToker lifeoflilybb begins with a meowing sound heard behind the door of a room, before a cat appears when it is opened.

A voice in the video is then heard saying “hello,” after which the cat makes a vocalization that sounds like a high-pitched “hello.”

The video was shared with a caption that read: “When people question that I spend too much time with Charlie… atleast this guy responds to me đź’€”

Cats can be clever on various levels, but can they imitate human speech?

According to a January 2020 study published in the peer-reviewed Journal of Veterinary Science, cats use vocalizations to communicate with each other and “express their internal states.”

Cats have up to 21 different vocalizations, and pet cats are “able to create an efficient communication with humans, thanks to the flexibility of vocalization behavior,” the study found.

Cats may be capable of making “solicitation purr” sounds to manipulate humans, according to Karen McComb, a behavioral ecologist at the University of Sussex in the U.K. She is the lead author of a July 2009 study published in Current Biology.

In the study, McComb wrote: “Parallels have previously been drawn between the isolation cry of domestic cats and the human infant distress cry.”

The study found that “such a cry, embedded within the naturally low-pitched purr, is dramatically emphasized by cats in the context of food solicitation, and humans are highly sensitive to it.”

McComb said in a statement at the time: “Solicitation purring is probably more acceptable to humans than overt meowing, which is likely to get cats ejected from the bedroom.”

The latest viral video has delighted TikTok users, such as Tom, who simply wrote: “omg this is cute,” in a comment that received more than 16,000 likes.

Fallon Westlake wrote that the cat “says it [hello] in your accent!!!!!”

Holly Leana wrote: “Omg [oh my god] he talks [crying laughing emoji],” while Linds commented: “I like how he paused and was like wait I know that one!”
