So, cats is a euphemism the women? Bitches, man.

This is exactly like two of my cats who are brother and sister: Blue and Echo. They cuddle all day long, often smashed together in to one furry mass of cat. But then, for seemingly no reason, one of them (usually Echo the female who is much smaller than her brother) will suddenly go ham on the other. Oh how I wish the little furry creatures could talk.

They play-fight. Wild animals play-fight more aggressively than domesticated animals.

Yeah, that about sums it up...
