Comfortis Chewable Tablets

Fleas can be more than just annoying for pets and their families, they can put your pet's health at risk. They can be very uncomfortable for both dogs or cats, and they can even develop allergies towards them, a condition called flea allergy dermatitis (FAD). Fleas can also infect your pet with tapeworms, and commonly do, when your pet licks or bites and accidentally ingests them. Comfortis is a prescription flea treatment for dogs and cats. It contains spinosad, a type of insecticide that kills fleas and prevents infestations. Comfortis can start working within 30 minutes and provides 1 month of protection. It comes in a flavored chewable tablet, making it easier to give. Comfortis is available in separate formulas for dogs and cats.
