It's amazing to hear the wide range of sounds that cats make. Neko has at least 20 different vocalizations, if not more. If I figure out how to put audio on here, I will upload some. for example, she goes "mrr" when she jumps, "mmphh" when she gets a shot, and let's not forget her heat noises that keep everyone on our floor up all night! I have never heard anything like it, and I've pretty much owned cats all my life. Although, the cats of the 21st century are much smarter than those born before. The cat downstairs goes "row row roww?" when I call his name. It's like he's trying to talk. I should do some research and studies on cat sounds, as it could be interesting and useful to know.
