He's got a urinary obstruction. I thought it might be an intestinal blockage because he was straining all morning and vomiting, plus his abdomen was hard. Vet said to get him in ASAP, so we rushed in and they said he has to be treated immediately. I was NOT expecting the outrageous bill they presented me to pay! Talk about adding insult to injury. When I called husband to tell him the news, he said what about just euthanizing the cat, but I cannot in good conscience do that to a 5yo animal that is such a huge part of our family. Fingers crossed he responds to the treatment and can come home Friday (or sooner)!
