More good news...he tested negative! She called us this evening and said she just LOVES him and thanked us for letting her have him. She will be e-mailing photos and I will post just as soon as I receive them. We just feel so happy about this, and it's so unusual to have it happen this way. Oh, she said that everyone at the vets office kept saying to her "are you sure you want THIS cat"? "You really don't want this one"! "We have so many here, why take a feral"? She told us she just had to have him and is SO happy! She also said he hisses at her, but as soon as she pets him he starts purrrrrring. My heart swells!
