I am treating Butter with Revolution for fleas and ticks. It also contains the heartworm preventative. Until I started seeing this "cats only" vet, Dr. Robinson never suggested it for him. Since we have to go see Dr. Anderson about every 5-6 weeks for Butter's skin, she just applies it when we are there. I guess its one of those "better safe than sorry" things. It is $12/dose when he gets it.
