Mittens is a cat in a cutaway gag set up by Brian when he vows to be harder to find than a nice cat in "Brian the Closer" when he has to avoid Quagmire for 72 hours in order to keep him from backing out of the purchase of a dump of a condo.

When Mittens owner checks on the cat's litter box, she finds a message regarding her miscarriage spelled out in the cat's feces and only laughs about the incident.
