Final answer:
Mrs. Wright in Susan Glaspell's play 'Trifles' had a pet bird, which is connected to the theme of her constrained life and is symbolized by the broken birdcage mentioned in the play.
Step-by-step explanation:
In Susan Glaspell's play Trifles, Mrs. Wright had a pet bird. The existence of the bird is inferred from the presence of a birdcage and dialogue between the characters Mrs. Peters and Mrs. Hale. The bird's presence is symbolic, representing Mrs. Wright's lost cheerfulness and her life before marriage. The text suggests that Mr. Wright may have killed the bird, just as he stifled Mrs. Wright's spirit. The birdcage, with its broken door, symbolizes Mrs. Wright's own confinement and her emotional state. There is no evidence of a cat; in fact, Mrs. Wright was afraid of them, which suggests the bird's demise was not natural.
