This Clever Cat Invented a Special 'Secret Language' Just to Communicate With His Blind Sister
The stereotype that cats are antisocial is exactly that, a stereotype. Cats can be incredibly affectionate, especially with each other.
Analia Serebrenik, who goes by @analia383 on TikTok, is a mom to two adorable cats, Fil andDoja. Doja does not have eyes, rendering her fully blind. But her brother, Fil, has created an entire feline language just to communicate with her and let her know where he is and what he's up to. Analia shared their special interactions on her social media.

The little sounds Fil makes for Doja are distinct and not at all like a typical meow from your average cat. They're clearly specifically for her. Analia hypothesized in the video that they're his way of letting his sister know he's making sure he's watching over her.
Commenters on the post were quick to point out the uniqueness of the situation and Fil's communication style:
"That's almost identical to the sound that mama kitties make to call their kittens."
"I just saw a post that cats don't typically vocalize to each other, only to humans, so this is extra special."
"I hear 'I love you' in there...what a darling boy."
What Cat Vocalizations Mean
Even without a blind cat sibling, cats have a plethora of different vocalizations that you can hear from them. The standard ones we're all familiar with; purring means a cat is content, whereas hissing means they're aggravated and warning you. But there are more in the mix, as well. Chirping can indicate excitement, trilling is a kind of a greeting, and the typical meow is the most common way cats communicate with humans. Yowling or howling is a sign of distress, something more high-pitched and sharp can mean they're surprised, and if your cat growls they're certainly telling you to "back off."
Most pet owners become incredibly tuned in to the different ways their animals communicate. It's pretty remarkable when you can learn the language that your pets have with each on top of the language that they use with you.
