No not mean, but some can sure be spirited.
I have a couple of females that will fight with my shoe as I shoo her from an apposing female.
It's hilarious, I'll move her away and she'll go strait back. I'll use my foot to nudge her away and she'll growl at it, smack at it with her hands and chew it if I keep it still.She'll do the same thing with the broom.
Sometimes she just so determined I dare not put my hands on her to move her, she'll chomp right into me.
There's no fear, pure anger because she can't rip the eyes out of the other female.
Let either one of these girls get pregnant and they are the sweetest I own, after it's back "I'm the boss not you".
But I'm bigger, good thing too.
I can just imagine how a new owner would feel with one of these gals.
I'm so glad their mine, I'm spirited too.
