Hi there and thank you for using pet coach to address your concern. Blood work was not performed prior to the sedation and if there is a pre-existing condition, the anesthesia may have made the condition worse and more pronounced. I would also consider a fructosamine test to check and see if the level is consistent with diabetes. I would say that the ultrasound is the next appropriate diagnostic test to have performed with what is going on. I hope this helps better determine what the cause could be. Please let me know if you have any other questions or concerns.

    Sorry to hear about this. Given that he recently got sedated, I am most suspicious that this is some reaction to the sedation. Different animals will metabolize medications differently and it's also possible that he may have some decreased function in his kidneys or liver that has caused this reaction. There are other complications that are possible, but I assume your vet would have checked, or is treating for those. The treatment that your vet did for the abscess sounds appropriate for the condition. This is unfortunately a rare complication. The urine test seems to be normal (glucose can end up in the urine when they are stressed). Hopefully further tests will help identify the problem. Zuzek will likely start to feel better with fluid therapy and a little time, so it's good they have him in the hospital. I know this is stressful, but hang in there and hopefully you'll get some good answers soon. I hope that helps and Zuzek gets better soon.
