A beautiful something
Ah, okay, one of my cats does that ^-^

:3 If you listen, sometimes It sounds like Blllrrrrrp XD

What is blurping?

Blurping is what I call her kitty ‘hum’ It’s kinda like a meow while she’s purring, but she never opens her mouth.
I’ll see if I can’t get a video of her doing it :)
