It's funny when they talk to us. Sometimes, when I notice Miko is making some really interesting sounds, I run to grab my phone to video record it, but he somehow knows whenever I have my camera on & stops. So I need to be really stealthy about it lol
Also, not sure if Diablo and Star are like this but, Miko will only talk to me. I do spend the most amount of time with him, but my mom tells me that whenever she is home alone with Miko, he is not vocal at all (as in he makes no meow sounds). But as soon as I get home from work, he starts meowing and demanding food/play and whatnot
