I had to rush Gatsby to the vet this morning with a urinary tract blockage. He's never even had a UTI before, but last night I noticed he was spending longer than usual in the litter box, and by early this morning he couldn't go at all. Needless to say, Gatsby and I were waiting at the door when the vet clinic opened.
They got him unblocked right away, but he'll be staying there at least through the weekend to make sure he doesn't block right up again. And then I'll have to figure out how to get him to drink more water and eat a special diet. Fortunately, because he has his own room (my home office), I won't have to worry about keeping him away from the other cats' food.
Thank goodness I knew from reading PT that I was dealing with a very serious issue! I really hope we can keep things under control by some means short of surgery.
