Oooo! I hope everyone gets normal again!
Maddie did this same thing. She would poop hard, small poopies. After the second day, she was in obvious discomfort during her bowel movements, but the rest of the time. I still decided to take her to the vet.
She actually had developed a bowel infection from chewing on sticks outside and they had become lodged!
I fecal exam was done to determine this. They also did an xray and we could see her blockage was from butt to almost stomach. It happened really fast.
I hope your problems are not this serious, but keep it in mind.
