UNREALISTIC ELEMENTS?

Hello everyone! I got to thinking the other day about whether or not we should include the option to have some unrealistic elements here on Reductio Ad Absurdum. By this I mean things such as unrealistically coloured eyes. I do not mean things such as neon green fur or wings and such, rather a normal looking dog with, say, red eyes. So we could still keep this place semi realistic. I just wanted to know what your thoughts on this would be? Feel free to state your opinions and suggestions c:

Personally, I'm very conflicted on this idea as I would like to keep this place at least somewhat realistic and not have hundreds of mutated canines running around but perhaps the apocalypse somehow let off some sort of radiation which slightly altered the canines to have certain supernatural elements?
