My silly boy cat likes to announce everything he's about to do. Jump up on something? Go use the kitty litter? Karate kick the door open because he wants food right now (he just did that while I was typing this, it is the only way he knows how to open doors) it's all just little baby innocent sounding meows.
Then when he gets the zoomies, he enjoys a good yodel at the top of his lungs.
Then my sweet little girl cat just enjoys chattering away at me. She also has little high pitched baby meows and sometimes does a call and response with me when I say her name. She's honestly such a sweetheart. I get the impression that when she chatters at me, she's telling me how excited and happy she is.
