Mickey was racing up and down the hallway dragging his bum and looking like someone was chasing him. I picked him up and he had poop hanging from his bum. I looked at it and its hanging from thread! My boyfriend had sewn a button on my pants last night and must have left out a piece. I cut the string and left it like it is but I dont know what to do! We gave him sone treats and now hes lying on the bathroom flooor. Anyone have any suggestions? Will it just pass through?
