This is a very interesting question. Current scientific thinking is NO.
The viruses causing cat flu and similar respiratory infections are quite specific to this species and there is no evidence that they can be transmitted to humans.
However, viruses are clever things and as we have seen with the bird flu and swine flu outbreaks, there is a theoretical possibility that these feline viruses could mutate (change) to become infectious in humans.
I must stress that this is simply theoretical and has not been yet seen.
