Okay--The first thing you need to do after you put all the sneezers in one area of the house, is to get everyone that is still well vaccinated for the 'basic' feline problems such as Rhinotracheitis, calici, and panleukopenia (FVRCP). Do you know if there is a mobile vet in your area that can come out and vaccinate your cats (at least the well ones for right now)?

Your veterinarian should ALWAYS be consulted first and foremost when your pet's welfare is at stake.
