I have heard that lightern(white) bunnies tend to attract more ticks. When I found my lionhead, Mr. Tumnus, in the field near my parents house he was COVERED in ticks. Most of them were around his ears and and neck/back area. I had to pull them all out and one had lodged itself so deep inside the area had become all infected and inflamed. I never really even knew we had ticks in the area until then. I would say that rabbits who are outdoors shouldnt come into contact with ticks all that often unless they are near or running through tall grassy areas.
