There have been a few instances where the developers have changed the artwork on certain traits. It can be assumed that cats with the original artwork will never be able to be reproduced (which would make them more rare). Do you have an original?
Serpent – changed to have thicker eyelids.
Onyx – changed to have white whiskers instead of black.
Pouty – changed to have less of a smile.
Ganado – changed the side diamonds and chest diamond so their colors no longer match the side color and chest color.
Calicool – a change so minor, I’ll bet you’ll never see it. Go ahead, give it a try. I dare you.
- Last kitty with original artwork: 44x,xxx?
- First kitty with new artwork: 45x,xxx?
