Welcome! I've made an Immutable base for you guys so that you won't have to put so much energy into the drawing, and more into the design itself! Even if you'd rather not use a base for your Immutable, I suggest you read through this to see the design "limitations," but they're really more like required traits! Let's do it! Immutables are-- for the most part-- normal cats, besides the fact that they cannot d-e. Here are the required traits! Instead of mouths, (which they gain only on Fridays, during the Fog event) they possess dual stripes on either side of their muzzle. These can vary! As long as they are stripes. Immutables have pale eyes that mimic the color they were in life, with a faint glow that pulses with their heartbeat. Their bl--d color changes to the same color as their eyes, and this also sparkles and pulses, glows. Most wounds on an Immutable will heal in mere seconds, but to mark them for their "sins," there is an ever-bl--ding scrape anywhere on their body. It also pulses and glows, sparkles, and does not close. Finally, the fog trail. Immutables leave behind a trail of fog in their wake, and this fog can be any pale/pastel color you wish, but it pulses with the cat's heartbeat. The weird circle under the bust view is for this. by the way, your cat CANNOT have any official accessories YET, because I haven't made the project for that yet, and an Immutable cannot have another animal companion yet for the same reason.
