Fellow cat owner- do you have any idea why she is licking my charger?

Evidently it tastes interesting. Cats are strange about tastes and textures. As long as she’s not biting it (could electrocute herself), it’s OK. Might be there’s sweat or something on the cable that she’s after? If she starts batting, biting, or scratching it, I’d suggest distracting her with something else that won’t zap her for biting it.
