If someone had told me when I started this thread that it would end like this I would have never believed it.

We took Neko to be boarded at a vet clinic tonight. The woman who runs the shelter that we adopted him from made the arrangements for us. They will keep him at the clinic for observation for a few days and if everything looks okay (i.e. he's not a mean cat) they'll place him in a home/shelter with other positive cats. The Vet Assistant that took him from us tonight told me that they know of a few homes where people look after positive cats.

I think that we all need some time to get over this whole ordeal. We'll probably still get a second cat but not right away.

Thanks to everyone here for your advice about cats and support when things went downhill. You all made this much easier for me.
