Well, Caly was trying to go both inside and outside the litterbox this morning without success, so I called the vet. Seems my regular vet will be out of town this afternoon, so they said, "Sorry, try someone else." So I took him to a vet in the next town over, where Kiri was hospitalized during her last days.

The vet thought Caly might not be blocked because his bladder wasn't too full, but he's going to try to find a way to ease the little guy's discomfort. So it's another day of hospitalization for poor Cal. He and I are both entirely stressed out at this point.
