Abstract: A disposable pet excrement collection device comprises a mantle piece with a broad-mouth opening and an inner space to receive collected pet excrement. The mantle piece converges at its opposite end to form a closed tip. The mantle piece is foldable from a flat storage configuration to a funnel-shaped configuration ready for use. The collection device includes at least one shutter at the broadmouth opening and a pull cord attached to the shutter. The pull cord is routed through the closed tip and, when the end of the pull cord that is routed through the closed tip is pulled, the shutter closes to thereby containing the excrement that has been collected.
