I have a 12-pack of Advantage Orange received as a gift. One of our cats is over 9 pounds - about 18 pounds to be exact. Since
Advantage Orange is for cats in the 1 - 9 pound range, is is OK to simply use two tubes (maybe a day apart to avoid a drippy mess) to dose the 18 pounder?
No, it is not recommend that you do this. You can apply one application and 2 weeks later apply another. vetcare
