I will be updating a lot of my OCs with more specific information about their species.

Info I'm not ready to publicize yet will be hidden with [redacted] or "?" labels.

KDU - kittydog universes ( encapsulates the entire multiverses my OCs live in including Void, Timeline, ?, and others. They have their own laws of the universe which seperates them from "normal" universes, which is why it's specified.)

KDU cats / KDU dogs are technically an original species due to them having different internal anatomy from normal cat/dog species from our universe. They follow rules of the KDU. Externally the species may not look "original" since theyre just colorful cats and dogs on the outside.

I will not specify too much as to what the internal distinctions are. I have them planned and written personally but they are not public.

Technically i am the only one who can make an authentic KDU oc, because the info designating their species is private. 

If you want to make a KDU oc now, you can try, but since you don't know what the internal anatomy differences are from a normal cat or dog furry oc, it likely won't be accurate. They could be their own AU ocs that you made or something but it won't be an authentic KDU character.

Also, i consider all kittydogs that aren't part of the kittydog story to be non-KDU kittydogs.

I plan for KDU oc anatomy distinctions to be public in the undetermined future (when i make the kittydog story public.) But for now some info won't be public because I don't want some of my ideas being ripped off before making the story official.
