Well.... No. I mean, they have trouble seeing anyway, so they would be classified as "blind" if tested to human standards, but it's a long drawn out thought process to make this idea.
I was just going to have a guy with a perk which granted him a ferret as a pet, specifically as signature gear so it doesn't get GM targets painted on it, at first. Then I thought about what psionic powers the guy was going to have(mostly pyro stuff), and one idea was "A eagle in every liver", or rather, a targeted attack to the vitals which cooked it a bit, then summoned a flaming eagle from it, dealing more damage and bringing out a minion which was also very on fire.
Then I thought about making my ferret also able to be "summoned", turning him from a semi-harmless pile of d'aaw into a fire shooting pile of d'aaw with a cute little helmet.
Then I thought "y'know what's better then having a cute little death ferret? BEING a cute little death ferret!", and then I had to make a Wereferret character because it's hard to be taken seriously when you weight less then a kilogram and make one of the worse traits out there look super cute(hoarding/stealing).
I'm not just making a character for the hell of it, though. This character is going to be in a game. With another person.
