The FeLV-positive cat must be prevented from having any contact with the negative cats, perhaps by housing it in a separate room within the house. Separate feeding utensils and litter pans should be provided, and hands should be thoroughly washed and clothing (including shoes) after handling and caring for the positive cat. The positive cat should never be allowed outdoors, where it might come into contact with FeLV-negative cats and transmit the virus.
