A pet owner revealed in a viral TikTok video what her new kitten does every time she starts speaking, and internet users can't cope with how sweet it is.

The heartwarming clip, shared in June by @pennybabyyy, shows the woman holding her tuxedo kitten close as they chill together in bed, whispering loving words to him while he purrs at her every time she says something to him.

"My new kitty starts purring every time I speak," says layover text in the clip. A caption adds: "Welcome to the fam [family] Jason Tatum." Newsweek reached out to @pennybabyyy for comment via TikTok comments. We could not verify the details of the case.

Whether cats love us or not is still not fully understood. However, science is clear about something: they can surely form strong and meaningful bonds with their owners, and they even miss us when we are away. A 2019 study by the Oregon State University says that cats exhibit the same attachment to their owners that babies show toward their parents.

In the study, cats, just like babies, acted distressed when their owners went away, and appeared to be happy and secure when they returned.

While dogs among other animal species, are very clear in showing their humans affection, cats can be way more subtle, so understanding how your feline feels about you is not always easy, but it is definitely not impossible.

An article published by Catster, medically reviewed by Dr. Luqman Javed, says that observing a cat's behavior when they are near you is the best way to tell how they feel about you.

One way your cat may show affection to you is by meowing; in fact, adult cats usually meow only to attract our attention or demand food or cuddles. Perhaps the biggest sign a feline loves you is them rubbing their head against you, marking you as "theirs."

Other signs include rolling on the floor and showing you their belly; purring when they are near you; sleeping on top or near you; grooming you like a kitten; kneading your arms or lap; and slow-blinking at you. By slow-blinking back, you can say you love them, too.

The video quickly went viral on social media and has so far received over 5.6 million views and more than 1.5 million likes on the platform.

One user, Robin, commented: "The fact cats can't control their purring and it's actual happiness is so sweet."
