The official ref sheet from a few years ago.

In short, Miro is the main sona and Madkat Miro aka "Madkat" is the possessed alternate form of Miro when certain....circumstance occurs. How did Miro get possessed by a feline jester spirit? Why is it rubber? Wonderful questions that will be answered..........at a later date. ^__^;;

You usually won't see Madkat unless something happens grinds Miro's gears.

Now here they are when they are not sharing a body.
