Mortimer
She'd appointed Tony as babysitter while she met with the DA regarding a court testimony she was due to give the following morning. The meeting had taken not only her lunch break, but an additional half hour and she was feeling mildly guilty at having wasted her friend's afternoon with mere puppy-watching.
He's on his back, sprawled across her emergency futon, sound asleep. Ziva's apparently decided to keep him company, curling into his side, recruiting his shoulder as a pillow. And Mortimer, of course, has wedged himself between the two, in absolute puppy bliss.
Abby considers the afternoon not wasted.
