Well, I spoke with the vet and apparently Nino has had a fever since yesterday, so he is on antibiotics for that. They don't know what is causing it at the moment as he is not showing any signs of not being well. He still hasn't made a poo for them to analize but she said that could be the technicians fault by not reading the card as it is stipulated they need a stool sample. Apart from that he is eating & drinking well and upon another examination seems very healthy and in no pain. He will be staying another night for observation and will be having a blood test to check for Feline Aids/Leukemia. She also talked about FIP, but said she will put that on the back burner for now.
She also thanked me so much for stepping up and rescuing Nino as he is so loveable and beautiful.

May I have some prayers that everything turns out well for this gorgeous boy.
I would hate my efforts to turn sour on me.
