We had a problem with similar symptoms...but our vet told us it was- i can't think of that word, but the one that kittens get that there isn't much of a survival rate. I was a wreck so I let my husband make the call being that he was a farmer and better able to look objectively. I still regret the decision we made to put the poor little guy down, especially because our vet really pushed the money issue on us. I can't help but think that .... well you know. Anyhow my point was that I know how heartbreaking a sick little one can be so I will pray that your story turns out much happier.
