All the posing that goes on -- Daisy growling at Boo if he so much as grazes her as she's falling asleep. Boo randomly swatting Daisy in the face for no reason at all. My coming home after a 40-hour-or-so workday to find tufts of hair, with roots attached, strewn around the house, indicating some sort of interspecies warfare had gone on in my absence.
It's like 90 degrees in the house today, but look who still wants to cuddle -- and not with me:
Note Boo's tail wrapped protectively around Daisy's bottom. Just too much.
