A rabbit had feasted on cardboard boxes

After checking on the teeth and finding them normal wear and tear, I asked: "Did the rabbit eat wires?"
"No," the lady said.
"He eats cardboard boxes. I have just shifted to a new apartment."

Moving to a new apartment, the rabbit feasted on the cardboard boxes. The slim young lady said that he passed sticky stools of small amount and was not his usual active self.

I felt the stomach distended with a soft mass. The rabbit was given drips but still did not pass much stools. I asked the owner to X-ray the rabbit the 2nd day and the X-rays showed stomach impaction.  Full of cardboard pieces!  No more free roaming without supervision now!
