very high temp

Last night Leo seemed a bit off. I didn't worry TOO much about it, I thought he might have just been in the middle of a sleep cycle when we woke him up. He was shivering, but that isn't uncommon with kittens you wake up out of a cozy nap. But it was a bit more than that. This morning he still seemed very off, so I held him for a bit, which he let me do - which was off - and then he decided he wanted to get down. He jumped from the sofa to the floor, a matter of a foot and a half - a small matter for him.. well he cried out and held up one foot. I went over to him, and he didn't seem to be injured, just sore. I put him back down and he had a bit of trouble walking, and then laid right down. I picked him up again, put him down again, same results. I called the shelter. They didn't want me to bring him in to the vet, they wanted to see him. They took his temp - which was off the charts, stopped at 106.4 where the thermometer stopped. He has been on clindamyacin for the calcivirus, so now they want him on clavamox, which I have never been a big fan of for kittens unless its an abscess. I brought him home, and called the vets to see what they would recommend. They recommended zithromax and fluids... which the shelter failed to mention (thinking about it, fluids would be a very good idea) Now I'm in a quandary.. I don't want the shelter to think I don't trust them, but I don't trust them!! arrgh. My friend at the vet said to give him a few hours, then call the shelter back and ask about the fluids and what not. I know zithromax is quite expensive, but it works!! why make the poor little guy suffer. He is sooo cute.. I bet I could get some good pictures of him like this :)

I just have to wonder,, what kind of training has the girl at the shelter had..
