Myanimese
In a Nutshell...
Myanimese, as the name implies, is a language mostly spoken by cat species, noteably Tabbians. The best way to describe it would probably be "when humans make those sort of annoying fake cat noises, except it's an actual language". It's very heavy in M and N sounds, like in the work "meow" and "nya". Yes, they're aware it sounds like most anime. You don't have to bring it up.
Naming Conventions
Well, look, basically most human name that starts with N or M becomes "Nya" and "Mya". Other than that, it's pretty much the same dialect. Like... Matt would be Myatt.
