Hi froggie098, yes I have heard of/seen this with several breeds, it is generally called "chirping" or "chattering". Just for fun here's some trivia... Cats can make over 100 distinct sounds... Dogs can only make about 10
I have 7 cats and they all do that. Its normal. Especially for my youngest cat Cream Puff. When we got her she only had 2 legs. And its hard for her to hunt but she gets one every once in a while. And she does it all the time. I thing I should as a question about her.
