I had to stay home all day yesterday waiting for the plumber, who eventually arrived and took our toilet apart. The culprit was the lid of a can of cat food. There is only one member of this household who would put that there; we'll have to see that empty cans and their lids go right into recycling bin and that it stays closed. We also have had to go around the apartment closing window latches; Sasson thinks opening them is great fun. Well, we wanted an intelligent cat, and we got what we wished for.
