I had a message from the morning vet. Oscar is doing well. His urine is flowing very well through the catheter but they are keeping him for another day as there is still some "grit" in his urine. I don't know if that is crystals or something else.

He'll call me this afternoon with an update.

Although it is more expensive this option keeps him on IV fluids and they wait until the bladder is well flushed out. It's worth it. HE'S worth it.

Even with my other two cats here, it's very quiet.
