Our really sick kitty

So, Monday morning I woke to find mr. p booting up breakfast in the kitchen and by evening it was very apparent that he could not keep anything down including water and was much sicker than we had thought. Tuesday he was sleeping in the morning when I went to work but by the time Jessica was heading out at noon piddy was super sick again re-igniting all worries from the previous day. At 5 we went to see the vet and it was not good. Aside from being a mess from dehydration, electrolyte and kidney production-wise, he was running a low temp. and when his belly was pressed on he started wailing.....I had to leave him overnight to be put under and x-rayed. The vet's big guess was a horrible theory about string and the digestive tract which was ruled out by the physical and the radiographs. Wednesday morning I spoke with the vet who informed me that the x-rays showed a blockage of some kind in the small intestine...but it was not apparent if this was actually the cause of all the sickness...so the decision was made to give p some valium to stimulate his non-existent appetite give him some food and water and wait. At 1:30 things were seeming good he had eaten and was holding it down...but then a call at 4 that he threw up again and as it had smelled like feces it was clear that this was coming up from somewhere deep in the intestines....next step. I was able to come take him home for the night since he had been pumped up with an IV of fluids and ulcer medication but need to return to the vet for a second set of x-rays on Thursday morning. Jessica and I looked at the x-rays and tried to get a better idea from the vet of what might be next depending on what happens with limited success. I'll update tomorrow....
