Cheshire and Chloe Pretending to be Friends

Looking through my cat photos from January, I'm shocked by what I see.  Cheshire and Chloe look like best friends!  It's as if the cats in the photos aren't the same cats that I live with every day.

They're not total enemies; they do sometimes fall asleep near each other, and they lounge around together sometimes.  But they do spend a large amount of time chasing each other around, with a good amount of growling and some hissing thrown in too.
