In Gentle Giant's song Black Cat it starts as follows:
There's a cat prowling through the streets at night
And she's black and her eyes are burning yellow
My question is: although said cat is referred as "she" and then the lyrics keeps it female, "...her eyes..." it doesn't mean it's a female cat, right? My guess is that in folk language "cat" assume the grammatical female gender, although it should be neutral, thus referred as it, according to many books. And, I'm also guessing cats are assumed to be grammatical female because in German we say "Die Katze", and both English and German are Germanic languages.
