House (2004)

S5E18 Here Kitty

Morgan is employed at a nursing home, where she shares her space with a peculiar pet cat that has an uncanny ability to curl up next to those nearing death. When the cat appears to indicate its own impending demise, Morgan becomes convinced her own time is running out. In a desperate attempt to seek help, she pretends to have a seizure, hoping to get House to diagnose her before it's too late.
