rescue my cats

I have two cats, a grandmother and grand daughter. They are both fixed but need shots. My husband has been ill and we have been told it is aggrivated by allergies probably the cats. They are usually indoors. We did not have the extra money to vaccinate them this year, but they seem to be in good health. I live in Kansas City North. Please help if we can not find a good home we will have to take them to the pound.
