Can You Use Frontline Plus for Cats on Dogs?

The flea and tick preventative treatment Frontline Plus has a different formula for cats and dogs, and the treatments should not be applied interchangeably. Dogs and cats process the flea and tick medication differently, so each must receive the correct type of medication.

The Frontline Plus formulas used for dogs and cats differ because each species of animal processes the chemicals found in Frontline Plus in a different way. Frontline Plus products should not be used on other animals, such as rabbits. However, Frontline Spray can be used by either species. Owners should consult with a veterinarian regarding what type of flea and tick preventative to use for cats and dogs.
