...is at the emergency vet right now. We came home from work today and noticed that he was lethargic, had weird posture and was wobbly on his back legs, was hunched over the water dish, looked bloated, and seemed to be in pain. Called the after-hours vet, who recommended we bring him in right away. The vet confirmed that he has a urinary blockage, which can be life threatening, so I am glad we did. They have to sedate and catheterize him tonight, and look for the cause of the blockage. Treatment options depend on what they find. If it is bad enough, one option is surgery to turn him into a girl cat. I wish I were kidding. (This should all sound very familiar to nypinta and everyone who read her "Stanley" post last week.)
That's all I know right now. Keep your fingers crossed for the little feller.
UPDATE (9:15pm): The vet just called. He was definitely blocked and they removed it. Bloodwork shows some toxins had built up and his kidney function was affected. Looks like we got him there in time to prevent the worst stuff. We'll have a better idea tomorrow. He will remain sedated and under observation overnight. Our regular vet will take over his care tomorrow morning. We're hoping for no more updates tonight because in this case, "no news is good news." They did mention that he is pretty young to be having these problems and they are likely to recur without some kind of intervention.
