@maggiedemi, I have no idea - can't tell. I always guess until they are caught or I get a good look at their nono area. But I had no idea calicos are usually female so I guess it's safe to assume she is. Which makes me want to have this cat fixed soon - the kitten is more adolecent age approaching 1 year - judging from size. Also heard a fight outside so maybe SHE was fighting a tom??
