INTRODUCTION: A unique, convenient applicator for you. The Vet-Kem® Applicator is specially designed to make applying flea and tick control easier, more precise - and neater - than ever before. You simply insert the appropriate Vet-Kem® tube for your cat/kitten into the applicator, close it and squeeze to apply. The applicator’s ergonomic, contoured shape makes it easy to grip and a built-in tip helps to spread the cat’s/kitten’s hair to allow the liquid to more readily reach the skin. The tube is sealed inside, so you can be confident that the liquid goes onto your cat/kitten - and not your hand.

Vet-Kem® Flea And Tick Spot On® For Cats is a topically applied long-lasting, flea and tick treatment product specifically formulated for cats and kittens with an insect growth regulator (IGR) which prevents flea eggs from maturing into biting adults. It also contains the highly effective flea, deer tick, and mosquito killing agent Etofenprox, which kills biting adult fleas, deer ticks, and mosquitoes your cat/kitten may acquire from its surroundings. A single application of Vet-Kem® Flea And Tick Spot On® For Cats will provide flea egg hatch inhibition for up to 30 days. Each package contains enough product for 3 monthly applications (90 days of protection). Vet-Kem® Flea And Tick Spot On® For Cats provides relief from flea infestations for up to 1 month by killing adult fleas and flea eggs on your cat or kitten. Adult fleas can live on your cat while producing vast numbers of eggs, which drop off your cat and develop in the surrounding environment. Vet-Kem® Flea And Tick Spot On® For Cats kills adult fleas and flea eggs, breaking the flea life cycle and providing your cat/kitten relief from flea bites at the same time.

After application, your cat’s/kitten’s skin oils carry Vet-Kem® Flea And Tick Spot On® For Cats over your cat’s/kitten’s body for protection against biting adult fleas and the development of flea eggs. Once adult fleas are evident on your cat/kitten, there is likely an infestation of flea eggs and flea larvae in your home. To completely kill the existing flea population, you may need to treat your home and your cat’s bedding (home sprays, foggers), as well as your yard (yard spray) with traditional flea products approved for use on pets, around the home, or in your yard. Vet-Kem® Flea And Tick Spot On® For Cats can be used in conjunction with other Vet-Kem® premise products. As with all flea products, Vet-Kem® Flea And Tick Spot On® For Cats is most effective when used as part of a total program aimed at reducing all stages of fleas in the cat’s/kitten’s environment. Vet-Kem® products are designed to complement each other in an integrated program for flea, deer tick, and mosquito management. To assure proper treatment, we recommend use of Vet-Kem® products as directed to treat all pets in the household, as well as the indoor and outdoor home environments.
