Best for Everyday Use
Bottom Line

With 100 chewable pills, not only is this a great solution to protect small pets and cats from fleas, ticks, and mosquitos by masking the bug-attracting CO2 they naturally exhale, each bottle will keep them covered for a whole 100 days.

Pros

100 tablets per bottle. Tasty liver flavor. Repels fleas, ticks, and mosquitos. Vitamin enriched supplement. For cats and dogs.

Cons

Remember, this product repels biting bugs, and will not kill an infestation already on your pet.

Whether you want to take your pet on a long walk in the park, on vacation, or just outside to do their business, you run the risk of exposing them to a wide range of biting insects every time they go outside. Fleas, lice, ticks, mosquitoes, flies, gnats, and other nasty bloodsuckers don’t just leave itchy welts behind, as they are all capable of transmitting horrible diseases that may have long-term effects on your pet’s health. Keeping a bug repellant on hand for your pet is a smart move, but it’s up to you to research the best formula to protect the cats and dogs in your care from bug bites.
