Bogart seems to be recovering very well from his bout with a urinary tract blockage.
In my call with the vet yesterday I learned that the very elevated creatinine level (19+) was back down to normal (2.0). His electrolytes are also back in balance. It's really an amazing recovery.
He's due to have his catheter removed on Thursday. If he can pee on his own, he's good to come home. I'm very hopeful and all the indications are good.
Until then, he's in the hospital wearing a cone with tubes sticking out of him.
When I visited him on Tuesday, he was much livelier than after his bladder flush and catheterization on Monday. He got so excited to see me that I was afraid he'd pull all his tubes out and I had to restrain him from leaping out of the little wall cubicle he was in.
His appetite is back with a vengeance. He hadn't eaten anything since Saturday and was only just licking a bit of gravy by Tuesday morning. He had a mostly full dish of food when I visited him Tuesday afternoon, which he attacked vigorously and finished when I was there. Later in the day, the vet told me he was eating voraciously.
Assuming all things go well on Thursday and he's got through this ordeal, there are a lot of things to mind going forward. He'll be on a urinary health formulated diet in perpetuity (yes, it's expensive). I'll also look into other supplements for urinary health. I'm also looking at pet insurance. I'm hard-pressed to cover the costs of this unexpected emergency ($2000.00+) and fear the possibility of recurrence (see below).
I've read several heartbreaking accounts of people who've lost cats due to urinary tract blockage. Basically, after 24 hours of blockage, the toxins build up and become deadly. Untreated, the cat can die—painfully—within six days.
I got Bogart in after maybe 48 hours blockage. He seemed fine Saturday morning, though I recall that we was licking himself a lot and seemed to be trying to pee on the carpet. Saturday night he was clearly uncomfortable, but I assumed it was constipation. I honestly had no idea about the likelihood of a urinary tract blockage. It's a risk for male cats (small wee-wees = small urethrae that block easily). I was giving him a tincture to help soften his stool and expecting any time he'd push out a massive dookie and be OK.
Recurrence is a big concern. Most of the accounts I read, which are likely the worst scenarios, mention that the blockage came back and back. There is actually a procedure (perineal urethrostomy) to remove the male cat's penis and suture in a wider urethra. That's pretty radical. My hope is that diet, supplements, and close monitoring of his water intake will keep him healthy for years to come.
