My one-year-old cat, Pam, makes several different types of noises. Apart from the usual meows and it’s variations, she also make a “trill noise”, with varying permutations. It sounds like “brrrrr”, basically. She also will often make a flat mmm noise like humming, but that’s not what I consider a trill.
My new kitty, Lucinda, who is, yes, just as cute in real life as she looks, has only ever made normal meows. She’s never trilled, although Pam communicates to her a lot with her trilling. I’ve met lots of cats that don’t trill, and only a few that have. Is this a genetic thing, occurring in only certain types of cats? I do note that Pam has always been extremely vocal, and in fact, when I got her as a 4-month-old in March, she was the subject of a thread seeking advice on shutting her up. She meowed constantly for weeks. She doesn’t do that anymore, very much. My new kitty is the opposite, there- she very rarely meows from day one.
What’s the deal with the trill?
