Dustin is an active and sweet guy with some special requirements: he is FeLV positive, which means he needs to be the only cat in the household OR he needs to be with other FeLV+ cats. FeLV, or Feline Leukemia, is a virus that can cause severe anemia and/or suppress the immune system. It is spread through close contact like mutual grooming, sharing water/food bowls and litter boxes, bite wounds, and from mother to kitten. Important things to know about FeLV: FeLV is only contagious to other cats. No other species can acquire FeLV, including dogs, birds, hamsters, or humans. Also, the virus is fragile and doesn't live long outside the cat's body. Right now, Dustin does not exhibit any signs of illness!
