How well I know that, KAK! That is why I was so worried about the extra cathing. Ming's usual vet wasn't in and I got Mr. Grumpy vet who has a very cold and matter-of-fact manner. He told me that there was a good chance they wouldn't be able to recath him because of that. He recathed fine, however. A reblockage is not unusual for Ming. He usually has to be recathed at least once before all the crystals are completely gone. That is why when I went to pick him up today I asked if he had peed on his own. They told me that they thought they has smelled urine in his litter box so they decided to release him (wtf?) Well, just before they were bringing him out, he reblocked. I could have told them this, but I'm not the vet, am I? I will be so glad to talk to Ming's regular whitecoat tomorrow. She is super!
