This hilarious yet unsettling short comedy by Stage Left Theatre ensemble member Mia McCullough focuses on a young suburbanite troubled by the pitter–patter of little paws in her attic. Turns out a squirrel is chewing up the insulation of the beautiful new home she lives in with her husband–who hates squirrels and refuses to share his wife’s bed as long as the critter is crawling around above them. As the woman wrestles with how–and whether–to get rid of the rodent, it becomes clear that McCullough is really writing about a couple’s response to an unplanned pregnancy. Under Jeremy Wechsler’s skillful direction, Maggie Graham’s mercurial performance superbly melds humor and poignancy as she charts the chilling compromises marriage entails. a Through 9/17: Mon 9 PM, Prop Thtr, 3502 N.
