Okay so normally Tuulikki and Tove get along, but lately they've been having some squabbles. No full on fights, and no chattering yet, but they take turns chasing one another away from food and now they're spraying each other. I went to the "sow behavior" thread to see if this specific behavior had an explanation but found nothing. Should I be concerned? Do they make each other unhappy? :C I don't want them to be stressed.
