And I'm not there! He had been hovering in the 200s the last couple of weeks, and I thought it was just a bounce. But right after I left on Friday he started going up into the 300s. Yesterday and today he went into the 400s. His pmps shot tonight was 415. When I started thinking about it today, I realized Zoozey has been using the litterbox a bit more often, and when my mom cleaned out the box today, she said there were a lot of pee clumps even with more than one cat using the box. So I'm thinking he may have a uti., which is why I told her to take him to the vet first thing tomorrow. She feels like she's failed him, but I told her she's doing a great job. In hindsight, the higher readings I've been getting the last couple of weeks make me think he's been on this track for a few weeks now. With him being at my parents' house the last month (I was there with him until Fri) and now with me gone, I think he's just a bit stressed. The good news is that he acts like he's feeling fine. He's eating, playfighting (his favorite playtime activity), and exploring. Is a uti a likely explanation? I'm afraid his spreadsheet isn't updated-my internet access has been spotty lately, but my mom does have Zoozey's bg log, which has every bg reading that's ever been taken on him which I told her to take to the vet tomorrow. And she's been recording his numbers too. And as soon as she gets her vet's fax number, I'm going to have them fax over Zoozey's records, which will have all the info about his dka. Am I leaving anything out?
